zone.js provides a flag DISABLE_WRAPPING_UNCAUGHT_PROMISE_REJECTION to let zone.js
throw the original error instead of wrap it when uncaught promise rejection found.
But the rejection value could be anything includes primitive value such as number.
In that case, we should not attach any additional properties to the value.

In Ivy, template type-checking has 3 modes: basic, full, and strict. The
primary difference between basic and full modes is that basic mode only
checks the top-level template, whereas full mode descends into nested
templates (embedded views like ngIfs and ngFors). Ivy applies this approach
to all of its template type-checking, including the DOM schema checks which
validate whether an element is a valid component/directive or not.
View Engine has both the basic and the full mode, with the same distinction.
However in View Engine, DOM schema checks happen for the full template even
in the basic mode.
Ivy's behavior here is technically a "fix" as it does not make sense for
some checks to apply to the full template and others only to the top-level
view. However, since g3 relies exclusively on the basic mode of checking and
developers there are used to DOM checks applying throughout their template,
this commit re-enables the nested schema checks even in basic mode only in
g3. This is done by enabling the checks only when Closure Compiler
annotations are requested.
Outside of g3, it's recommended that applications use at least the full mode
of checking (controlled by the `fullTemplateTypeCheck` flag), and ideally
the strict mode (`strictTemplates`).

Though we currently have the knowledge of where the `key` for an
attribute binding appears during parsing, we do not propagate this
information to the output AST. This means that once we produce the
template AST, we have no way of mapping a template position to the key
span alone. The best we can currently do is map back to the
`sourceSpan`. This presents problems downstream, specifically for the
language service, where we cannot provide correct information about a
position in a template because the AST is not granular enough.

There is an inconsistency in overrideProvider behaviour. Testing documentation says
(https://angular.io/guide/testing-components-basics#createcomponent) that all override...
methods throw error if TestBed is already instantiated. However overrideProvider doesn't throw any error, but (same as
other override... methods) doesn't replace providers if TestBed is instantiated. Add TestBed instantiation check to
overrideProvider method to make it consistent.
BREAKING CHANGE:
If you call `TestBed.overrideProvider` after TestBed initialization, provider overrides are not applied. This
behavior is consistent with other override methods (such as `TestBed.overrideDirective`, etc) but they
throw an error to indicate that, when the check was missing in the `TestBed.overrideProvider` function.
Now calling `TestBed.overrideProvider` after TestBed initialization also triggers an
error, thus there is a chance that some tests (where `TestBed.overrideProvider` is
called after TestBed initialization) will start to fail and require updates to move `TestBed.overrideProvider` calls
before TestBed initialization is completed.

This commit refactors the `ExpressionTranslatorVisitor` so that it
is not tied directly to the TypeScript AST. Instead it uses generic
`TExpression` and `TStatement` types that are then converted
to concrete types by the `TypeScriptAstFactory`.
This paves the way for a `BabelAstFactory` that can be used to
generate Babel AST nodes instead of TypeScript, which will be
part of the new linker tool.

Let's say we have a code like
```html
<div<span>123</span>
```
Currently this gets parsed into a tree with the element tag `div<span`.
This has at least two downsides:
- An incorrect diagnostic that `</span>` doesn't close an element is
emitted.
- A consumer of the parse tree using it for editor services is unable to
provide correct completions for the opening `<span>` tag.
This patch attempts to fix both issues by instead parsing the code into
the same tree that would be parsed for `<div></div><span>123</span>`.
In particular, we do this by optimistically scanning an open tag as
usual, but if we do not notice a terminating '>', we mark the tag as
"incomplete". A parser then emits an error for the incomplete tag and
adds a synthetic (recovered) element node to the tree with the
incomplete open tag's name.
What's the downside of this? For one, a breaking change.
<ol>
<li>
The first breaking change is that `<` symbols that are ambiguously text
or opening tags will be parsed as opening tags instead of text in
element bodies. Take the code
```html
<p>a<b</p>
```
Clearly we cannot have the best of both worlds, and this patch chooses
to swap the parsing strategy to support the new feature. Of course, `<`
can still be inserted as text via the `<` entity.

NG_VALUE_ACCESSOR is a multi injection token, users can and
should expect more than one ControlValueAccessor to be
available (and this is how it is used in @angular/forms).
This is now reflected in the definition of the injection token
by typing it as an array of ControlValueAccessor. The motivating
reason is that using the programmatic Injector api will now
type Injector#get correspondingly.

NG_VALUE_ACCESSOR is now typed as a readonly array rather than
a mutable scalar. It is used as a multi injection token and as

in the XMLHttpRequest patch, when get `readystatechange` event, zone.js try to
invoke `load` event listener first, then call `invokeTask` to finish the
`XMLHttpRequest::send` macroTask, but if the request failed because the
server can not be reached, the `load` event listener will not be invoked,
so the `invokeTask` of the `XMLHttpRequest::send` will not be triggered either,
so we will have a non finished macroTask there which will make the Zone
not stable, also memory leak.
So in this PR, if the `XMLHttpRequest.status = 0` when we get the `readystatechange`
event, that means something wents wrong before we reached the server, we need to
invoke the task to finish the macroTask.

In #38666 we changed how ngcc deals with type expressions, where it
would now always emit the original type expression into the generated
code as a "local" type value reference instead of synthesizing new
imports using an "imported" type value reference. This was done as a fix
to properly deal with renamed symbols, however it turns out that the
compiler has special handling for certain imported symbols, e.g.
`ChangeDetectorRef` from `@angular/core`. The "local" type value
reference prevented this special logic from being hit, resulting in
incorrect compilation of pipe factories.
This commit fixes the issue by manually inspecting the import of the
type expression, in order to return an "imported" type value reference.
By manually inspecting the import we continue to handle renamed symbols.

Common AST formats such as TS and Babel do not use a separate
node for comments, but instead attach comments to other AST nodes.
Previously this was worked around in TS by creating a `NotEmittedStatement`
AST node to attach the comment to. But Babel does not have this facility,
so it will not be a viable approach for the linker.
This commit refactors the output AST, to remove the `CommentStmt` and
`JSDocCommentStmt` nodes. Instead statements have a collection of
`leadingComments` that are rendered/attached to the final AST nodes
when being translated or printed.
