This commit updates the timeout used in the incremental hydration tests from `101` -> `10` ms, which allows to speed up tests by ~20% (12.5 -> 10 seconds locally).

There were type mismatches and or unintended any types that were preventing nested timers from accessing the delay value during hydration annotation processing.

This cleans up the triggering code base and consolidates it down to one
function that outlines the logic. This also resolves the `hydrate when`
behavior issue.

This commit removes a custom `whenStable` util in favor of standard `ApplicationRef.whenStable` API.
There is also an important different between the custom `whenStable` function and `ApplicationRef.whenStable` implementation: the `whenStable` was caching the "stable" promise on per-ApplicationRef basis, which resulted in unexpected behavior with zoneless, when some code ended up getting a stale resolved promise, when an application was not stable yet, this causing order of operations issues. This commit also has an extra test that covers that case.

When hydrating a tree of blocks, this prevents cleanup from firing more than once per tree. It also ensures the cleanup happens after hydration has finished.

If a defer block is nested inside control flow while also being nested
underneath a defer block all using incremental hydration, timing issues
prevented the child nodes from being properly hydrated. This ensures
hydration happens on next render.

This commit addresses a problem with tests that use the `fit` function to focus on individual test cases. While these tests run successfully in the full suite, they fail when focused individually using `fit`.
The issue lies in the behavior of `withEventReply` and other hydration-related functions (i.e., `provideX`, `withX`). These functions return platform-specific providers based on the `ngServerMode` setting, causing inconsistencies between server and browser environments. As a result, provider instances cannot be reused across server and browser applications.
**Example of problematic code:**
```ts
const hydrationFeatures = [withEventReply()];
const html = await ssr(SimpleComponent, { hydrationFeatures });
// Expected behavior ...
const appRef = await prepareEnvironmentAndHydrate(doc, html, SimpleComponent, {
hydrationFeatures,
});
// Expected behavior ...
```
**Solution:**
To address this, we define `hydrationFeatures` as a function instead of a static array. This ensures that a new instance of `withEventReply` is created separately for each environment, eliminating platform-specific mismatches between server and browser contexts:
```typescript
const hydrationFeatures = () => [withEventReply()]; // Define as a function
const html = await ssr(SimpleComponent, { hydrationFeatures: hydrationFeatures() });
// Expected behavior ...
const appRef = await prepareEnvironmentAndHydrate(doc, html, SimpleComponent, {
hydrationFeatures: hydrationFeatures(),
});
// Expected behavior ...
```

This commit adds the `ngServerMode` as global, which allows for the tree-shaking of server-only code from the bundles. When this flag is unset at runtime, server-specific code will be excluded by Closure, optimizing bundle size.
**Internal Angular Flag:** This is an internal Angular flag (not a public API), avoid relying on it in application code.

hydrate triggers were firing in CSR cases and attempting to find parent defer blocks. This prevents that from happening. In these cases, the defer block id will be empty.
