In this commit, we're using the `from()` in the `adev-home` component, which allows us to invert a dependency and avoid memory leaks. Because an `async` function would be executed even if the component is already destroyed.

Updates the docs since we'll have support for template strings in 19.2. Also mentions that tagged template string aren't supported.
Fixes#59160.

In this commit, we tree-shake the `PreloadLinkCreator` for client bundles because it's targeting only server code. We use the pending tasks service to contribute to app stability by waiting for the module to load.

The new version is 2x smaller in the reduced code size; as thus this eliminates extra bytes. Refactors `joinWithSlash` function to reduce code size and improve readability. Added checks to handle leading and trailing slashes more concisely and provided comments for clarity.

We already have a function called `isDetachedByI18n` which checks whether a `tNode` is in `isDetached` state; as thus, there's no reason to apply those checks manually.

Before `resource()` resolves, its value is in an unknown state. By default
it returns `undefined` in these scenarios, so the type of `.value()`
includes `undefined`.
This commit adds a `defaultValue` option to `resource()` and `rxResource()`
which overrides this default. When provided, an unresolved resource will
return this value instead of `undefined`, which simplifies the typing of
`.value()`.

In this commit, we remove the separate `a === undefined` and `a === null` checks and replace them with `a == null`. Using `a == null` is better and more concise because it checks for both `null` and `undefined` in a single operation. The loose equality `==` is specifically designed to treat `null` and `undefined` as equivalent. This change only reduces some bytes in the code and simplifies it, with no performance impact, as modern JavaScript engines handle `a == null` efficiently. Additionally, comments have been added for clarification.

The `_checkParentType` bodies are wrapped with `ngDevMode`, meaning they act as no-ops in production. We can wrap the actual calls to `_checkParentType` with `ngDevMode` to prevent calling no-op functions in production

The `type_checks` module already exposes a utility function that checks whether `TNode.componentOffset` is greater than -1. There is no need to check that property manually in other places, as we can reuse the helper function.

Drops some bytes by moving `Accept` into a variable, which is then minified to something like `var a="Accept"` and reused in all the places.

In this commit, we prevent error handling when the root injector is already destroyed. This may happen when the observable completes before emitting a value, which would trigger a `catchError` block that attempts to call `runInInjectionContext` on a destroyed injector.

The `type_checks` module already exposes a utility function that checks whether `LView` is marked as a root view. There is no need to check flags in other places, as we can reuse the helper function.

If a file ends up in multiple programs, the unused imports migration was counting it twice. This was fine since the string replacements were handling it correctly, but it was printing out incorrect data.
These changes rework the migration to de-duplicate the replacements and produce the data from the de-duplicated results.

This commit updates a flaky test to increase the amount of work (more `for` loop iterations) to minimize the chance of getting the same timestamp after that work.

Makes the following cleanups in the output AST:
* The `TemplateLiteral` and `TemplateLiteralElement` nodes have been renamed to `TemplateLiteralExpr` and `TemplateLiteralElementExpr` respectively for consistency and to avoid overlaps with the expression AST nodes.
* The `TemplateLiteralExpr` and `TemplateLiteralElementExpr` have been refactored to be `Expression`s for correctness. This involves updating some existing code.
* The `TaggedTemplateExpr` has been renamed to `TaggedTemplateLiteralExpr` for consistency.

Reworks the lexer's scanner to produce more than one token at a time. This can be useful for the cases where one token means the end of another one.
Also cleans up the scanner by making all non-essential methods private and using strict equality everywhere.

Updates the HMR dependencies extraction logic to handle conditional expressions.
For example, `providers: [condition ? providersA : providersB]`.
