With this commit, the NgOptimizedImage directive will throw
a runtime error if it detects that one of the density descriptors
in rawSrcset is higher than 3x. It's generally not recommended
to use density descriptors higher than ~2, as it causes image to
download at very large sizes on mobile screens (thus slowing down
LCP). The density max is set conservatively to 3 in case apps
expect users to zoom in.
In future commits, we may want to throw even at densities >
than 2 and provide a configuration override for the zoom case.

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.

Refactoring tests made me realise that we are misinterpreting the

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.

This commit adds a `rawSrcset` attribute as a replacement for the
`srcset` attribute. The `srcset` attribute cannot be set statically
on the image directive because it would cause images to start
downloading before the "loading" attribute could be set to "lazy".
Changing the name to `rawSrcset` allows the directive to control
the timing of image loading. It also makes it possible to support
custom loaders for `srcset` file names. Rather than having to repeat
the image origin for each image, the existing `rawSrc` value and
image loader can be composed to generate each full URL string. The
developer must only provide the necessary widths for the `srcset`.
For example, the developer might write:
```markup
<img rawSrc="hermes.jpg" rawSrcset="100w, 200w" ... />
```
with a loader like:
```js
const loader = (config) => `path/${config.src}?w=${config.width}`;
```
and the img tag will ultimately be set up as something like:
```markup
<img src="path/hermes.jpg?w=100" srcset="path/hermes.jpg?w=100 100w, path/hermes.jpg?w=200 200w" .../>
```
PR Close#47082
Currently if you use a static `srcset` with the image directive,
lazy loading no longer works because the image would start to
load before the loading attribute could be set to "lazy". This
commit throws an error if you try to use `srcset` this way.
In a follow-up commit, a new attribute will be added to support
responsive images in a lazy-loading-friendly way.

This commit updates the `NgOptimizedImage` directive to drop the `standalone` flag and create a new NgModule which declares and exports it, so that the directive can be used in apps that use pre-v14 version of Angular.

The CI failed to run on the last PR, so we didn't catch
that there were web tests failing due to absolute/relative
URL issues. This commit should fix the issue.
PR Close#47082
Previously NgOptimizedImage would default to requesting
an image at the width matching the width attribute in
the image HTML. While this works for width attrs that
match the intrinsic size of the image (e.g. responsive
images or images sized with CSS), this can be a sharp
edge for developers who use the width/height attributes
to set rendered size (i.e. instead of CSS, which one can
do for a fixed size image). In this case, defaulting to
the width attribute for the requested image would mean
requesting always at 1x quality, so screens with a DPR
of 2+ get an image that is too small. Without a default
request width, the image served by the CDN would likely
be at intrinsic size, so 2x images would look correct.
This PR also updates the NgOptimizedImage sandbox and tests.

This commit updates the `NgOptimizedImage` directive as standalone, so it's easier to import it in

PR Close#47082
This commit updates the `NgOptimizedImage` directive to drop the `loader` input. Component-specific loaders can still be configured via `IMAGE_LOADER` token and the `loader` input was only useful in case different loaders have to be present in a single template, which doesn't seem to be a common case. We'll be able to re-introduce the input later if needed.

We want it to be clear what benefits the image directive
confers over a normal <img> tag, and the `NgImage` name

This brings the typing of ngStyle into parity with ngClass since commit
e2ab99b95e. Should help with some strict template checking edge cases.
PR Close#47069
With strict template type checking, a null/undefined value will raise an
error. However the implementation is completely fine with it, and it
would be pointless to "fix" it at the callsite and convert to e.g. an
empty string. Allow all of the "supported types" to be passed in
directly to ngClass.

To mitigate the effect of Observables with memory leak, this change clears
the `ChangeDetectorRef` when the `AsyncPipe` is destroyed. This avoids any
leak within the `Observable` to retain the view data. A test has been added
to verify that this change works correctly with promises that resolve _after_
the pipe has been destroyed.
Note: this is not marked as fix as `AsyncPipe` itself is _not_ leaking any
memory.

Updates us to version 4.0 of Jasmine and fixes some errors that were the result of us depending upon deprecated APIs. We need to do this both to stay up to date and because it was going to break eventually, because one of the Bazel packages was logging a deprecation warning that version 4.0 was required.
There were also some cases where the state of `ngDevMode` had started leaking out between tests.
