Fixes host listeners being inherited twice, if the sub class has its own `propMetadata`. This is related to #29170 which fixed something similar, however all of the test cases there had a super class with some metadata and a sub class that didn't have any. The issue manifested itself in the `MatTreeToggle` which inherits a listener from the `CdkTreeToggle` and adds an extra `Input` of its own, causing the listener to be added twice.

- Remove an extra type `ViewOrElement`, which even had the same numeric value as `View`.
- Updates comment to remove part about alleged bit-masking that we could be doing here.
We aren't using this with bitmasks, and if we were, everything would be a `NodeType.Container`,
because it's value was `0`.
- Updates the number values to be simple, human-readable integers, since we're not using these
with any kind of bit-manipulation.
- Add comments about each type.

HACK: This is NOT the correct implementation for deprecatedOverrideProvider.
We do not plan to implement this at all since the API is deprecated and
scheduled for removal in V8. This hack is here temporarily for Ivy testing
until we transition apps inside Google to the overrideProvider API. At that
point, we will be able to remove this method entirely. In the meantime, we
can use overrideProvider here to test apps with Ivy that don't care about
eager instantiation. This fixes 97% of cases in our blueprint.

Angular Ivy interprets inline static style/class attribute values as instructions that
are processed whilst an element gets created. Because these inline style values are
referenced by style/class bindings, their inline style values are applied at a later
stage. Despite them being eventually applied, their values should be applied earlier
before any directives are instantiated so that directive code can rely on any inline
style/class changes.
This patch ensures that all static style/class attribute values are applied (rendered)
on the element before directives are instantiated.

BREAKING CHANGE:
Certain elements (like `<tr>` or `<col>`) require parent elements to be of a certain type by the HTML specification
(ex. <tr> can only be inside <tbody> / <thead>). Before this change Angular template parser was auto-correcting
"invalid" HTML using the following rules:
- `<tr>` would be wrapped in `<tbody>` if not inside `<tbody>`, `<tfoot>` or `<thead>`;
- `<col>` would be wrapped in `<colgroup>` if not inside `<colgroup>`.
This meachanism of automatic wrapping / auto-correcting was problematic for several reasons:
- it is non-obvious and arbitrary (ex. there are more HTML elements that has rules for parent type);
- it is incorrect for cases where `<tr>` / `<col>` are at the root of a component's content, ex.:
```html
<projecting-tr-inside-tbody>
<tr>...</tr>
</projecting-tr-inside-tbody>
```
In the above example the `<projecting-tr-inside-tbody>` component culd be "surprised" to see additional
`<tbody>` elements inserted by Angular HTML parser.

Previously, ngtsc would resolve forward references while evaluating the
bootstrap, declaration, imports, and exports fields of NgModule types.
However, when generating the resulting ngModuleDef, the forward nature of
these references was not taken into consideration, and so the generated JS
code would incorrectly reference types not yet declared.
This commit fixes this issue by introducing function closures in the
NgModuleDef type, similarly to how NgComponentDef uses them for forward
declarations of its directives and pipes arrays. ngtsc will then generate
closures when required, and the runtime will unwrap them if present.

This fixes an issue with commit b6f6b117. In this commit, default imports
processed in a type-to-value conversion were recorded as non-local imports
with a '*' name, and the ImportManager generated a new default import for
them. When transpiled to ES2015 modules, this resulted in the following
correct code:
import i3 from './module';
// somewhere in the file, a value reference of i3:
{type: i3}
However, when the AST with this synthetic import and reference was
transpiled to non-ES2015 modules (for example, to commonjs) an issue
appeared:
var module_1 = require('./module');
{type: i3}
TypeScript renames the imported identifier from i3 to module_1, but doesn't
substitute later references to i3. This is because the import and reference
are both synthetic, and never went through the TypeScript AST step of
"binding" which associates the reference to its import. This association is
important during emit when the identifiers might change.
Synthetic (transformer-added) imports will never be bound properly. The only
possible solution is to reuse the user's original import and the identifier
from it, which will be properly downleveled. The issue with this approach
(which prompted the fix in b6f6b117) is that if the import is only used in a
type position, TypeScript will mark it for deletion in the generated JS,
even though additional non-type usages are added in the transformer. This
again would leave a dangling import.
To work around this, it's necessary for the compiler to keep track of
identifiers that it emits which came from default imports, and tell TS not
to remove those imports during transpilation. A `DefaultImportTracker` class
is implemented to perform this tracking. It implements a
`DefaultImportRecorder` interface, which is used to record two significant
pieces of information:
* when a WrappedNodeExpr is generated which refers to a default imported
value, the ts.Identifier is associated to the ts.ImportDeclaration via
the recorder.
* when that WrappedNodeExpr is later emitted as part of the statement /
expression translators, the fact that the ts.Identifier was used is
also recorded.
Combined, this tracking gives the `DefaultImportTracker` enough information
to implement another TS transformer, which can recognize default imports
which were used in the output of the Ivy transform and can prevent them
from being elided. This is done by creating a new ts.ImportDeclaration for
the imports with the same ts.ImportClause. A test verifies that this works.

This update aligns this behavior between Ivy and VE: now default selector is used for Components when it's needed.

With 6215799, we introduced a schematic for the new static-query timing.
Currently when someone runs the update schematic manually within his
CLI project (the schematic does not run automatically yet), he might have
noticed that the migration is executed for the same `tsconfig` file multiple
times. This can happen because the `getProjectTsConfigPaths` function
can incorrectly return the same tsconfig multiple times. The paths are not
properly deduped as we don't normalize the determined project tsconfig paths

Currently the static-query migration does not properly handle functions which
are declared externally. This is because we don't resolve the symbol of the
call-expression through its type. Currently we just determine the symbol of the
call-expression through the given call expression node, which doesn't necessarily
refer to the *value declaration* of the call expression. e.g. the symbol refers to the
import declaration which imports the external function. This means that we currently
can't check the external function as we couldn't find the actual value declaration.
We can fix this by resolving the type of the call expression and using the type in order
to retrieve the symbol containing the *value declaration*
PR Close#29133
Currently when the static-query runs for a project with multiple TypeScript
configuration files (e.g. a usual CLI project), the migration incorrectly
applies the code transformation multiple times. This is because the migration
is currently based on the source file contents in the file system, while the
actual source file contents could have already changed in the devkit schematic
tree.

With 6215799055, we introduced a schematic
for the Angular core package that automatically migrates unexplicit
query definitions to the explicit query timing (static <-> dynamic).
As the initial foundation was already big enough, it was planned
to come up with a follow-up that handles asynchronous query
usages properly. e.g. queries could be used in Promises,
`setTimeout`, `setInterval`, `requestAnimationFrame` and more, but
the schematic would incorrectly declare these queries as static.
This commit ensures that we properly handle these micro/macro
tasks and don't incorrectly consider queries as static.
The declaration usage visitor should only check the synchronous
control flow and completely ignore any statements within function
like expressions which aren't explicitly executed in a synchronous
way. e.g. IIFE's still work as the function expression is
synchronously invoked.

Currently with ViewEngine, if someone runs the platform's
`bootstrapModule` method in order to boostrap a module in
JIT mode, external component resources are properly resolved
*automatically*.
Currently with Ivy, the developer would need to manually call
`resolveComponentResources` in order to asynchronously fetch
the determined external component resources. In order to make
this backwards compatible with ViewEngine, and also since
platforms can already specify a `ResourceLoader` compiler
provider, we need to automatically resolve all external
component resources on module bootstrap.
--
Since the `ResourceLoader` is part of the `@angular/compiler`,
because ViewEngine performed the factory creation in the compiler,
we can't access the `ResourceLoader` token from within core.
In order to workaround this without introducing a breaking change,
we just proxy the `ResourceLoader` token to `core` through the
compiler facade. In the future, we should be able to move the
`ResourceLoader` to core when ViewEngine code no longer exists in
the `@angular/compiler`.

Sometimes declarations are not exported publicly but are exported under
a private name. In this case, rather than adding a completely new
export to the entry point, we should create an export that aliases the
private name back to the original public name.
This is important when the typings files have been rolled-up using a tool
such as the [API Extractor](https://api-extractor.com/). In this case
the internal type of an aliased private export will be removed completely
from the typings file, so there is no "original" type to re-export.
For example:
If there are the following TS files:
**entry-point.ts**
```ts
export {Internal as External} from './internal';
```
**internal.ts**
```ts
export class Internal {
foo(): void;
}
```
Then the API Extractor might roll up the .d.ts files into:
```ts
export declare class External {
foo(): void;
}
```
In this case ngcc should add an export so the file looks like:
```ts
export declare class External {
foo(): void;
}
export {External as Internal};
```

Previously, when the NgModule scope resolver discovered semantic errors
within a users NgModules, it would throw assertion errors. TODOs in the
codebase indicated these should become ts.Diagnostics eventually.
Besides producing better-looking errors, there is another reason to make
this change asap: these assertions were shadowing actual errors, via an
interesting mechanism:
1) a component would produce a ts.Diagnostic during its analyze() step
2) as a result, it wouldn't register component metadata with the scope
resolver
3) the NgModule for the component references it in exports, which was
detected as an invalid export (no metadata registering it as a
component).
4) the resulting assertion error would crash the compiler, hiding the
real cause of the problem (an invalid component).
This commit should mitigate this problem by converting scoping errors to
proper ts.Diagnostics. Additionally, we should consider registering some
marker indicating a class is a directive/component/pipe without actually
requiring full metadata to be produced for it, which would allow suppression
of errors like "invalid export" for such invalid types.
