Add an abstract class that has a default implementation of the run
function and visits all nodes. Authors of template checks can extend
this class and override the `visitNode` method to return diagnostics.

Currently the error message functions are defined as static methods on a class which means that as soon as one of them is used somewhere, all of them have to be retained. This isn't a problem at the moment, because all of them are behind `ngDevMode` checks, but it's error prone and it's easy to fix.
These changes move them out into functions so that they can be imported individually. It also has the advantage of allowing Webpack to minify the function names.

In anticipation of the removal of the View Engine npm package output,
the integration tests of ngcc are switched to use @angular packages for
from npm. The version 12 packages are guaranteed to always be View
Engine format which makes them suitable to be processed in the ngcc
integration tests.

The current naming causes tsickle to emit `/** @implements {ZoneDelegate} */ class ZoneDelegate ...`, which is a cyclic definition error in Closure Compiler. Additionally, the name shadowing is also confusing to humans.

Previously, the decorator transformer was annotating the synthesized properties with TS type annotations. However, because it ran after the JSDoc transformer, the TS types were just dropped from the emitted JS. Attempting to move the decorator transformer before the JSDoc transformer causes tsickle crashes because synthetic AST fragments are not attached to a SourceFile node.

Return `TemplateDiagnostic` instead of `ts.Diagnostic` when getting the
extended template diagnostics. This makes the integration with the

This method is the @angular/language-service side of the implementation
for https://github.com/angular/vscode-ng-language-service/issues/1485
Given a location in a file, if the location is inside a component,
`getTemplateLocationForComponent` will return the `DocumentSpan` of the
inline `template` or the `DocumentSpan` for the file that the
`templateUrl` points to.

The current behavior of `routerLink` for `null` and `undefined` inputs is to treat
the input the same as `[]`. This creates several unresolvable issues with
correctly disabling the links because `commands = []` does _not_ behave the same
as disabling a link. Instead, it navigates to the current page, but will also
clear any fragment and/or query params.
The new behavior of the `routerLink` input will be to completely disable navigation
for `null` and `undefined` inputs. For HTML Anchor elements, this will also mean
removing the `href` attribute.
Fixes#21457Fixes#13980Fixes#31154
BREAKING CHANGE:
Previously `null` and `undefined` inputs for `routerLink` were
equaivalent to empty string and there was no way to disable the link's
navigation.
In addition, the `href` is changed from a property `HostBinding()` to an
attribute binding (`HostBinding('attr.href')`). The effect of this
change is that `DebugElement.properties['href']` will now return the
`href` value returned by the native element which will be the full URL
rather than the internal value of the `RouterLink` `href` property.

Previously with View Engine output, the `enableResourceInlining` option
could be set to inline external templates and styles (also for the
resulting `.metadata.json` files). We want to do the same for the Ivy
compilation pipeline (regardless of the compilation mode). The full
compilation definitions, and partial declarations currently already
inline resources in a way that no external requests need to be made.
Although there is one exception currently. These are the calls for
setting class metadata (for testbed overrides). This commit updates
the set class metadata calls (for both partial and full compilation)
to always inline resources. This means that libraries do not need
to start shipping external styles/templates just for the
`setClassMetadata` calls.
Note: Only doing this for partial compilation has been considered, but
it seems like it would be simpler implementation-wise to do this for
full compilation as well. Given the external resources are already
inlined (through their `ecmp` definitions), it seems acceptable (or
even more aligned) to do the same for the set class metadata calls.

The previous behavior of `RouterLink` for `null` and `undefined` inputs was to treat
the input the same as `[]` or `''`. This creates several unresolvable issues with
correctly disabling the links because `commands = []` does not behave the same
as disabling a link. Instead, it navigates to the current page, but will also
clear any fragment and/or query params.
The new behavior of the `routerLink` input will be to completely disable navigation

The server transition initializer looks for some `style` tags and clears them based on their `ng-transition` ID. The way we currently have the logic creates a couple of intermediate arrays just so we can call `forEach` at the end.
These changes use a regular `for` loop with an `if` statement instead. This isn't a _massive_ performance improvement, but the logic does run during app initialization which is performance-sensitive and it's an easy change to make on our end.

Class static properties with initializers that cause code execution (for example, call expressions or new expressions) have the potential to cause side effects at module evaluation. This is similar in effect to module level code. As a result, optimizers can not safely remove a class with such a static property as the potential side effects may have meaningful effects on the state of the application execution. To allow classes with these type of static properties to be optimized and removed if unused, the initializer expressions for the static properties can be annotated as pure. This annotation provides a signal to an optimizer that the expression does not have any potential side effects and is useful in cases where static analysis can not currently prove that there are, in fact, no side effects caused by the initializer.

The compliance tests can check source-map segments against expectations
encoded into the expectation files. Previously, the encoding of the expected
segment was only delimited by whitespace, but this made it difficult to identify
segments that started or ended with whitespace.
Now these segment expectations are wrapped in double-quotes which makes
it easier to read and understand the expectation files.

The management of `browserUrlTree` currently has several problems with
correctly tracking the actual state of the browser.
This change makes the Router eagerly update the `browserUrlTree` when
handling navigations triggered by browser events (i.e., not 'imperative'). This
is because with those types of navigations, the browser URL bar is
_already_ updated. If we do not update the internal tracking of the
`browserUrlTree`, we will be out of sync with the real URL if the
navigation is rejected.
It would be best if we could remove `browserUrlTree` completely, but doing that
would require a lot more investigation and is blocked by #27059 because
the SpyLocation used in tests does not emulate real browser behavior.
