Add an image loader for Netlify Image CDN. It is slightly different in implementation from existing loaders, because it allows absolute URLs
Fixes#54303
PR Close#54311
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.

As an ongoing effort to stabilize the NgOptimizedImage API before existing the Developer Preview, this commit renames the `rawSrc` attribute used for the NgOptimizedImage selector matching to `ngSrc`. The `rawSrcset` is also renamed to `ngSrcset` for consistency.
The motivation for this change is to align the attribute name better with other built-in directives, such as `ngFor`, `ngIf`, `ngClass`, `ngStyle`, etc.
Note: this is technically a breaking change, but since the NgOptimizedImage directive is in the Developer Preview mode, we land the change in a patch branch.

This commit cleans up some stylistic nits and
moves functions out of util.ts into files that
are more specifically named (url.ts and error.ts).

This commit updates the logic of Image Loaders to throw an error in case an absolute URL is provided an an input to the loader function. The loaders can construct URLs based on image paths relative to the bas URL configured for a loader.

This refactoring pulls url-related error reporting into one place.
It also makes sure that error messages and the related error
reporting logic are tree-shakable.

Refactoring tests made me realise that we are misinterpreting the
ensurePreconnect option - in fact it should configure the
PRECONNECT_CHECK_BLOCKLIST provider _only_ if the ensurePreconnect
is set to false.

This commit removes a nested describe block as it
does't add any value this point. Also moved the
utils tests to the bottom of the file as those are
less important as compared to the other tests.

This commit modifies the provideCloudinaryLoader and provideImageKitLoader functions to support an additional ensurePreconnect option, similar to the Imgix loader functions.
PR Close#47082
This commit updates the image loader tests to avoid creating the TestBed environment, since it's not really needed for the tests. Instead, the loader functions are invoked directly and the output is verified.

This commit modifies the provideImgixLoader function to support
an additional ensurePreconnect option. Other loaders could follow
the same pattern to support a similar option as well.
As more loaders get developed we will refactor code to streamline
the loader authoring and enforce consistency.

This commit adds a built-in Imgix loader for the
NgOptimizedImage directive. If you provide the
desired Imgix hostname, an ImageLoader will be
generated with the correct options.
Usage looks like this:
```ts
providers: [
provideImgixLoader('https://some.imgix.net')
]
```
It sets the "auto=format" flag by default, which
ensures that the smallest image format supported
by the browser is served.
This change also moves the IMAGE_LOADER, ImageLoader,
and ImageLoaderConfig into a new directory that will
be shared by all built-in image loaders.
