Add a test to ensure that optimized image loaders can be configured at any
level of the DI hierarchy, including component's node injector.
PR Close#47565
Previously the built-in image loaders for the optimized image directive
were tightly coupled to the preconnect checks infrastructure. This was
creating a problem when developers were trying to provide a loader on
a component level (or, more generally, deeper in the DI hierarchy):
- PreconnectLinkChecker is the application-level service, provided in root;
- it makes sense to provide loaders in different parts of the DI hierarchy;
This refactoring removes the PreconnectLinkChecker configuration from
the loaders infrastructure and makes it application-wide config. The
PRECONNECT_CHECK_BLOCKLIST is also a simple provider (it was a
multi-provider previously) which should make the overall configuration
easier.

Ensure that keyframes rules, defined within components with emulated
view encapsulation, are scoped to avoid collisions with keyframes in
other components.
This is achieved by renaming these keyframes to add a prefix that makes
them unique across the application.
In order to enable the handling of keyframes names defined as strings
the previous strategy of replacing quoted css content with `%QUOTED%`
(introduced in commit 7f689a2) has been removed and in its place now
only specific characters inside quotes are being replaced with
placeholder text (those are `;`, `:` and `,`, more can be added in
the future if the need arises).
Closes#33885
BREAKING CHANGE:
Keyframes names are now prefixed with the component's "scope name".
For example, the following keyframes rule in a component definition,
whose "scope name" is host-my-cmp:
@keyframes foo { ... }
will become:
@keyframes host-my-cmp_foo { ... }
Any TypeScript/JavaScript code which relied on the names of keyframes rules
will no longer match.
The recommended solutions in this case are to either:
- change the component's view encapsulation to the `None` or `ShadowDom`
- define keyframes rules in global stylesheets (e.g styles.css)
- define keyframes rules programmatically in code.

Currently, the `RouterLink` and `RouterLinkWithHref` classes share a lot of common code (with some special logic around handling `<a>`-related scenarios). This commit unifies the logic of the mentioned directives by moving the necessary handling to the `RouterLink` directive and making it a parent one for the `RouterLinkWithHref` class (i.e. class RouterLinkWithHref extends RouterLink).
This is the first step in upcoming unification to merge both directives and just keep `RouterLink` one (it'd be done in followup PRs).

Currently the code that creates a root component assumes that it's always going to deal with a single component definition which won't work with host directives. These changes rework the code so that it's able to apply multiple directives, allowing us to eventually add support for host directives.
I also tried to make the root component creation easier to follow by breaking it up into smaller functions.

This commit applies the changes similar to the ones performed for the `inject()` function in df246bb235.
The `TestBed.inject` function is updated to use previously added object-based API for options: now the flags argument supports passing an object which configures injection flags.
DEPRECATED:
The bit field signature of `TestBed.inject()` has been deprecated, in favor of the new options object.

1. Remove `zone-async-tagging` implementation from zone.js and move the
implementation to `@angular/core`, so `@angular/core` can import this
package more easily for better treeshaking.
2. Add `async tagging zone` implemenation into `@angular/core` package.
So we don't need to get the `AsyncStackTaggingZoneSpec` from `global`
instance, we can import the `class` directly for better treeshaking.
3. Only load this ZoneSpec when `ngDevMode` is `true`.

When reporting type-checking diagnostics in external templates we create a
`ts.SourceFile` of the template text, as this is needed to report Angular
template diagnostics using TypeScript's diagnostics infrastructure. Each
reported diagnostic would create its own `ts.SourceFile`, resulting in
repeatedly parsing of the template text and potentially high memory usage
if the template is large and there are many diagnostics reported. This commit
caches the parsed template in the template mapping, such that all reported
diagnostics get to reuse the same `ts.SourceFile`.

`TNode`s have the `directiveStart` and `directiveEnd` properties that indicate the indexes at which directive instances (including components) have been stored. Currently there are several places throughout the codebase which assume that if a component matches a node, its index will always be `directiveStart`.
As far as I can tell, we probably ended up accumulating these assumptions, because we needed a quick way of accessing the component instance and it happened to be conventiently stored at `directiveStart`. The reason why it's always stored at `directiveStart` is likely to match the lifecycle hook execution order from ViewEngine.
With host directives these assumptions won't be valid anymore, because we want the host directives to _always_ execute before the host component that they're on so that the host has a chance to override them. To achieve this we have to insert host directives before the component.
These changes address the issue by introducing a new `TNode.componentOffset` property which indicates the offset after `TNode.directiveStart` at which the component is stored. Furthermore, I've removed the `isComponentHost` flag since it was duplicating the information from `TNode.componentOffset` and I've audited and fixed all the places where we read `directiveStart` to account for the changed data structure.
Reasons for some of the decisions I made along the way:
* In the case of host directives, I decided to go against our current convention of executing the component lifecycle hooks before the directive, because lifeycle hooks are a chance to change the component state (e.g. in `ngOnChanges`) and running the component hooks first would allow the host directives to undo any overrides made by the host.
* I decided to go with a `componentOffset`, instead of a `componentIndex` indicating the exact index the component is at, because as the runtime is set up at the moment, it would be difficult to know what index the component is going to end up at. Another problem is that we appear to have some logic that moves the entire "directive window" by incrementing both `directiveStart` and `directiveEnd`. By using an offset, we don't have to worry about the index remaining correct.
