The ngcc tool adds namespaced imports to files when compiling. The ngtsc
tooling was not processing types correctly when they were imported via
such namespaces. For example:
```
export declare class SomeModule {
static withOptions(...): ModuleWithProviders<ɵngcc1.BaseModule>;
```
In this case the `BaseModule` was being incorrectly attributed to coming
from the current module rather than the imported module, represented by
`ɵngcc1`.

ctx.actions.declare_file now used in @angular/bazel ng_module rule as ctx.new_file is now deprecated. Fixes error:
```
File "ng_module.bzl", line 272, in _expected_outs

Use ctx.actions.declare_file instead of ctx.new_file.
Use --incompatible_new_actions_api=false to temporarily disable this check.

This can be worked around with incompatible_new_actions_api flag but may as well fix it proper so downstream doesn't require this flag due to this code.

Without this change when using UrlTree redirects in `urlUpdateStrategy="eager"`, the URL would get updated to the target location, then redirected. This resulted in having an additional entry in the `history` and thus the `back` button would be broken (going back would land on the URL causing a new redirect).
Additionally, there was a bug where the redirect, even without `urlUpdateStrategy="eager"`, could create a history with too many entries. This was due to kicking off a new navigation within the navigation cancelling logic. With this PR the new navigation is pushed to the next tick with a `setTimeout`, allowing the page being redirected from to be cancelled before starting a new navigation.

Previously, (presummably due to a typo) the `okToCacheOpaque` argument
of `DataGroup#cacheResponse()` was essentially never taken into account
(since opaque responses have a non-200 status code and thus `res.ok` is
always false).
This commit fixes the typo, which allows opaque responses to be cached
when `okToCacheOpaque` is true (i.e. in data groups using the
`freshness` strategy).

This commit doesn't change the behavior wrt caching, but it makes it
more explicit that only non-timed-out responses are cached. In case of a
timeout, `res` would be set to a programmatically created 504
`Response`, so `cacheResponse()` (which checks for `res.ok`) would not
have cached it anyway, but this makes change makes it more explicit (and
more similar to the equivalent part in [handleFetchWithFreshness()][1]).

Previously, opaque responses where handled a little differently than
other responses from the mock server. More specifically, they were not
tracked (so no assertions could be made for them) and their
[`Body` mixin][1] methods (such as `arrayBuffer()`, `json()`, `text()`)
would throw an error due to `body` being `null`.
This commit ensures opaque responses are also captured on the mock
server and also changes `Body` mixin methods to better simulate the
[spec'd behavior][2].
(These improvements will be necessary to test caching of opaque
responses in a subsequent commit.)

If an entry-point has missing dependencies then it cannot be
processed and is marked as invalid. Similarly, if an entry-point
has dependencies that have been marked as invalid then that
entry-point too is invalid. In all these cases, ngcc should quietly
ignore these entry-points and continue processing what it can.
Previously, if an entry-point had more than one entry-point that
was transitively invalid then ngcc was crashing rather than
ignoring the entry-point.

The Angular runtime frequently calls into user code (for example, when
writing to a property binding). Since user code can throw errors, calls to
it are frequently wrapped in a try-finally block. In Ivy, the following
pattern is common:
```typescript
enterView();
try {
callUserCode();
} finally {
leaveView();
}
```
This has a significant problem, however: `leaveView` has a side effect: it
calls any pending lifecycle hooks that might've been scheduled during the
current round of change detection. Generally it's a bad idea to run
lifecycle hooks after the application has crashed. The application is in an
inconsistent state - directives may not be instantiated fully, queries may
not be resolved, bindings may not have been applied, etc. Invariants that
the app code relies upon may not hold. Further crashes or broken behavior
are likely.
Frequently, lifecycle hooks are used to make assertions about these
invariants. When these assertions fail, they will throw and "swallow" the
original error, making debugging of the problem much more difficult.
This commit modifies `leaveView` to understand whether the application is
currently crashing, via a parameter `safeToRunHooks`. This parameter is set
by modifying the above pattern:
```typescript
enterView();
let safeToRunHooks = false;
try {
callUserCode();
safeToRunHooks = true;
} finally {
leaveView(..., safeToRunHooks);
}
```
If `callUserCode` crashes, then `safeToRunHooks` will never be set to `true`
and `leaveView` won't call any further user code. The original error will
then propagate back up the stack and be reported correctly. A test is added
to verify this behavior.

Our module resolution prefers `.js` files over `.d.ts` files because
occasionally libraries publish their typings in the same directory
structure as the compiled JS files, i.e. adjacent to each other.
The standard TS module resolution would pick up the typings
file and add that to the `ts.Program` and so they would be
ignored by our analyzers. But we need those JS files, if they
are part of the current package.
But this meant that we also bring in JS files from external
imports from outside the package, which is not desired.
This was happening for the `@fire/storage` enty-point
that was importing the `firebase/storage` path.
In this commit we solve this problem, for the case of imports
coming from a completely different package, by saying that any
file that is outside the package root directory must be an external
import and so we do not analyze those files.
This does not solve the potential problem of imports between
secondary entry-points within a package but so far that does
not appear to be a problem.

Some packages do not actually provide a `typings` field in their
package.json. But TypeScript naturally infers the typings file from
the location of the JavaScript source file.
This commit modifies ngcc to do a similar inference when finding
entry-points to process.

There are scenarios where it is not possible for ngcc to guess the format
or configuration of an entry-point just from the files on disk.
Such scenarios include:
1) Unwanted entry-points: A spurious package.json makes ngcc think
there is an entry-point when there should not be one.
2) Deep-import entry-points: some packages allow deep-imports but do not
provide package.json files to indicate to ngcc that the imported path is
actually an entry-point to be processed.
3) Invalid/missing package.json properties: For example, an entry-point
that does not provide a valid property to a required format.
The configuration is provided by one or more `ngcc.config.js` files:
* If placed at the root of the project, this file can provide configuration
for named packages (and their entry-points) that have been npm installed
into the project.
* If published as part of a package, the file can provide configuration
for entry-points of the package.
The configured of a package at the project level will override any
configuration provided by the package itself.

Previously each test relied on large shared mock file-systems, which
makes it difficult to reason about what is actually being tested.
This commit breaks up these big mock file-systems into smaller more
focused chunks.
PR Close#30591
To improve cross platform support, all file access (and path manipulation)
is now done through a well known interface (`FileSystem`).
For testing a number of `MockFileSystem` implementations are provided.
These provide an in-memory file-system which emulates operating systems
like OS/X, Unix and Windows.
The current file system is always available via the static method,
`FileSystem.getFileSystem()`. This is also used by a number of static
methods on `AbsoluteFsPath` and `PathSegment`, to avoid having to pass
`FileSystem` objects around all the time. The result of this is that one
must be careful to ensure that the file-system has been initialized before
using any of these static methods. To prevent this happening accidentally
the current file system always starts out as an instance of `InvalidFileSystem`,
which will throw an error if any of its methods are called.
You can set the current file-system by calling `FileSystem.setFileSystem()`.
During testing you can call the helper function `initMockFileSystem(os)`
which takes a string name of the OS to emulate, and will also monkey-patch
aspects of the TypeScript library to ensure that TS is also using the
current file-system.
Finally there is the `NgtscCompilerHost` to be used for any TypeScript
compilation, which uses a given file-system.
All tests that interact with the file-system should be tested against each
of the mock file-systems. A series of helpers have been provided to support
such tests:
* `runInEachFileSystem()` - wrap your tests in this helper to run all the
wrapped tests in each of the mock file-systems.
* `addTestFilesToFileSystem()` - use this to add files and their contents
to the mock file system for testing.
* `loadTestFilesFromDisk()` - use this to load a mirror image of files on
disk into the in-memory mock file-system.
* `loadFakeCore()` - use this to load a fake version of `@angular/core`
into the mock file-system.
All ngcc and ngtsc source and tests now use this virtual file-system setup.
