We were not properly passing around the TCB full program optimization,
so TCB generation was done per individual file. This significantly
slowed down reference resolution.

Currently when application source code references e.g. an NgModule that
points to references that aren't available, the compiler will break at
runtime without any actionable/reasonable error.
This could happen for example when a library is referenced in code, but
the library is simply not available in the `node_modules`. Clearly,
TypeScript would issue import diagnostics here, but the Angular compiler
shouldn't break fatally. This is useful for migrations which may run
against projects which aren't fully compilable. The compiler handles
this fine in all cases, except when processing `.d.ts` currently... and
the runtime exception invalides all other information of the program
etc.
This commit fixes this by degrading such unexpected cases for `.d.ts`
metadata reading to be handled gracefully. This matches existing logic
where the `.d.ts` doesn't necessarily match the "expecation"/"expected
format".
The worst case is that the Angular compiler will not have type
information for some directives of e.g. a library that just isn't
installed in local `node_modules`; compared to magical errors and
unexpected runtime behavior.

The use of relative imports vs. module imports and the existing mismatch
can cause symbols to be duplicated in migrations. This is problematic as
it breaks migration logic or compiler logic in the worst case.
Long-term we will solve this by having a better Bazel toolchain where
both relative and module imports can point to the same files; but in
practice this is not the case right now.
This commit fixes the fallback template logic in the signal
input/queries migration; in case no type check block information is
available.

When we check for duplicates in dev mode, we end up stringifying an `LView` even if we don't report an error. This can be expensive in large views.
These changes work around the issue by only generating the string when we have an error to throw.
Fixes#58509.

Angular components that use ShadowDOM view encapsulation have an alternate
execution path for adding component styles to the DOM that does not use the
SharedStylesHost that all other view encapsulation modes leverage. To ensure
that ShadowDOM components receive all defined styles, additional logic has been
added to the ShadowDOM specific renderer to also cover external styles.

This update corrects a grammatical error in the "CSS style properties" section of the template binding documentation. The sentence "You must create a new object instance when you modify these values in order to Angular to apply any updates" was updated to read correctly as "You must create a new object instance when you modify these values in order for Angular to apply any updates." This clarification helps improve readability and ensures the documentation communicates instructions accurately for readers.

When the compiler generates the `HostDirectivesFeature`, it generates either an eager call (`ɵɵHostDirectivesFeature([])`) or a lazy call (`ɵɵHostDirectivesFeature(() => [])`. The lazy call is necessary when there are forward references within the `hostDirectives` array. Currently we resolve the lazy variant when the component definition is created which has been enough for most cases, however if the host is injected by one of its host directives, we can run into a reference error because DI is synchronous and the host's class hasn't been defined yet.
These changes resolve the issue by pushing the lazy resolution later during directive matching when all classes are guanrateed to exist.
Fixes#58485.

Adjusts the HMR initialization to avoid the edge case where a developer makes change to a non-rendered component that exists in a lazy loaded chunk that has not been loaded yet. The changes include:
* Moving the `import` statement out into a separate function.
* Adding a null check for `d.default` before calling `replaceMEtadata`.
* Triggering the `import` callback eagerly on initialization.
Example of the new generated code:
```js
(() => {
function Cmp_HmrLoad(t) {
import(
/* @vite-ignore */ "/@ng/component?c=test.ts%40Cmp&t=" + encodeURIComponent(t)
).then((m) => m.default && i0.ɵɵreplaceMetadata(Cmp, m.default, [/* Dependencies go here */]));
}
(typeof ngDevMode === "undefined" || ngDevMode) && Cmp_HmrLoad(Date.now());
(typeof ngDevMode === "undefined" || ngDevMode) &&
import.meta.hot &&
import.meta.hot.on("angular:component-update", (d) => {
if (d.id === "test.ts%40Cmp") {
Cmp_HmrLoad(d.timestamp);
}
});
})();
```

The Closure Compiler used at Google has a property renaming optimization
that can change the property names when minifying code. Having the
correct type helps the TSJS team that develops a tool to identfy
property renaming issues directly in TypeScript.
