This change explicitly resets a reactive consumer before setting inputs
on directive instances. This is to assure that any potential input setters
do _not_ run in the reactive context.

When binding an array to `class` like `[class]="['foo', 'bar']"`, the runtime treats it the same as a literal binding with all the values being `true`, e.g. `{foo: true, bar: true}`. While object literals can only have string keys, arrays can have any value which can lead to errors if the array contains non-string values.
These changes add some logic to stringify the keys and ignore invalid ones.
Fixes#48473.

This commits update the platform-server test structure to add 2 applications in the Angular CLI workspace one based on ngmodules and another standalone. The same E2E suit is ran on both apps.

This commit updates hydration logic to handle cases when there are projection slots present in a template inside of an `<ng-container>` and when there are regular elements follow an <ng-content> slot (see tests for additional information). With this combination, the logic that annotates regular element locations should fallback to calculating a path from a reference node to that node. In case of an <ng-container>, the comment node is located *after* the node that needs an annotation. An existing logic was mistakenly returning an empty path, which was represented as a pointer to teh reference node. This commit fixes that and triggers a fallback to using a component host node as a reference in this case.
Resolves#49918.

This commit updates the platform-server integration tests to use the Angular CLI as it makes it easier to add more tests and remove the custom webpack setup.

Empty text nodes are not present in the server-rendered HTML output, thus we inject a special marker
at a text node location to later restore an empty text node at the client. Currently, we treat text nodes with spaces as "empty" as well, however those spaces are present in the HTML and text nodes are created in a browser. Adding extra annotation in this case results in extra text nodes created on the client and may trigger hydration issues. This commit updates the code to avoid treating text nodes with spaces as "empty".

This commit adds a phase to the template pipeline to merge `nextContext()`
instructions that follow each other without context reads in between. That
is, the sequence:
```typescript
nextContext();
var v1 = nextContext();
```
becomes:
```typescript
var v1 = nextContext(2);
```

This commit modifies the `ListenerOp` operation to capture the context
needed to generate the "correct" (per `TemplateDefinitionBuilder`) function
name for the handler function for the listener.

The `resetView` instruction in the template pipeline had a copy-paste error
where it was emitting a call to `reference` instead. This commit fixes the
issue.

This commit adds a chaining phase which post-processes reified template
pipeline operations, and collapses chainable instructions into chained
calls. Performing chaining as a post-processing step after reification
allows the specifically selected instruction variants to be known when
considering chaining two operations.

This commit adds a variable optimization pass to the template pipeline. The
pipeline generates all variables which might be referenced within a given
view's template function, regardless of whether other operations will read
those values.
The variable optimizer post-processes the IR and performs several variable-
related optimizations:
* It transforms variable declarations to side effectful expressions when the
variable is not used, but its initializer has global effects which other
operations rely upon.
* It removes variable declarations if those variables are not referenced and
either they do not have global effects, or nothing relies on them.
* It inlines variable declarations when those variables are only used once
and the inlining is semantically safe.

This commit teaches the template pipeline how to generate `textInterpolate`
when there's a single expression with no surrounding static text.

This commit reverses the generate template functions when adding them to the
constant pool in the template pipeline. This seems to better match the
ordering in which `TemplateDefinitionBuilder` generates template functions.
Further study is needed to determine if this is exactly accurate.

`advance()` was not emitted correctly by the template pipeline. There were
two problems:
* it was not handled in `transformExpressionsInOp()`.
* it was not added to the list correctly in `phaseGenerateAdvance()`.
This commit addresses both problems.

This commit fixes a broken assertion in the template pipeline concerning the
ownership of nodes in `insertBefore`, as well as adjusts a few other
assertions.

The template pipeline previously included an error when a static attribute
binding was found on an `<ng-template>`, under the assumption that this case
didn't happen in reality. It turns out that it does, so this commit removes
the error in favor of a comment to investigate the case further.

The template pipeline previously reified the parameters to `template()`
incorrectly. This commit adjusts the output to correctly reference the
attributes of the `template()` call.
