Based on the user agent stylesheet rules outlined in https://html.spec.whatwg.org/multipage/rendering.html#img-contain-size, images that have `sizes=auto` while applying `width: auto` or `width: fit-content` would be constrained to only 300px width.
This changeset overrides said user agent stylesheet rule with a much larger constraint, to avoid the problem.
Additionally, it introduces a filter `wp_img_tag_add_auto_sizes` which can be used to opt out of the functionality, as an additional measure.

This saves the `WP_Image_Editor` implementation that supports the queried options to a cache to avoid performing redundant compatibility checks, which can be expensive. For example, `WP_Image_Editor_Imagick::supports_mime_type()` can get called in the editor multiple times to determine which image formats can be supported during `wp_plupload_default_settings()`.
With this cache, the support will be stored for 1 day, speeding up loading times for the editor. This also introduces a new global caching group, `image_editor` to manage any subsequent caches that are related to image editor optimizations.

Introduces the filter `pre_attachment_url_to_postid` to allow developers to short-circuit the function `attachment_url_to_postid()`.
The return values are expected to be an attachment ID, zero (`0`) to indicate no attachment was found or `null` to indicate the function should proceed as usual.

A common use-case for the 'wp_get_loading_optimization_attributes' filter is to modify attributes based on the 'src' attribute. However, the `wp_img_tag_add_loading_optimization_attrs()` was not passing that attribute to the function as expected, which would make such usage of the filter unreliable. This changeset ensures the 'src' attribute is also passed in this scenario. All other calls to `wp_get_loading_optimization_attributes()` already included the attribute.

Automatically create a JPEG version of uploaded HEIC images if the server has
a version of Imagick that supports HEIC. Conversion is done silently through
the existing `WP_Image_Editor` infrastructure that creates multiple sizes of
uploaded images.
This allows users to view HEIC images in WP Admin and use them in their posts
and pages regardless of whether their browser supports HEIC. Browser support
for HEIC is relatively low (only Safari) while the occurrence of HEIC images is
relatively common. The original HEIC image can be downloaded via a link on

Chrome unreliably loads a lazy-loaded iframe when it is hidden using `clip: rect(1px, 1px, 1px, 1px)`. Instead of using `clip`, a lazy-loaded iframe can also be hidden with `visibility:hidden` which results in it loading not only in Chrome but all other browsers. With this change applied, the hard-coded check to prevent lazy-loading post embeds is now removed. An added benefit to using `visibility:hidden` is that the entire iframe in this case is not interactable, meaning that users navigating the document with the keyboard will not unexpectedly encounter tab stops inside of the hidden iframe, as can happen now with `clip` when the JS fails to reveal the loaded iframe. Note also that the `clip` property is deprecated.
Lastly, when such a post embed iframe is rendered in an RSS feed, the `style` attribute is now removed using the HTML Tag Processor as opposed to using string replacement.

In PHP 8.4, declaring function or method parameters with a default value of `null` is deprecated if the type is not nullable.
PHP applications are recommended to ''explicitly'' declare the type as nullable. All type declarations that have a default value of `null`, but without declaring `null` in the type declaration, will emit a deprecation notice:
{{{
function test( array $value = null ) {}
}}}
`Deprecated: Implicitly marking parameter $value as nullable is deprecated, the explicit nullable type must be used instead`
**Recommended Changes**
Change the implicit nullable type declaration to a nullable type declaration, available since PHP 7.1:
{{{#!diff
- function test( string $test = null ) {}
+ function test( ?string $test = null ) {}
}}}
This commit updates the affected instances in core to use a nullable type declaration.

Prior to this change, images added in shortcodes would be considered separately from all other images within post content, which led to incorrect application of the loading optimization attributes `loading="lazy"` and `fetchpriority="high"`.
This changeset changes the filter priority of `wp_filter_content_tags()` from the default `10` to `12` on the various content filters it is hooked in, in order to run that function after parsing shortcodes. While this may technically be considered a backward compatibility break, substantial research and lack of any relevant usage led to the assessment that the change is acceptable given its benefits.
An additional related fix included is that now the duplicate processing of images is prevented not only for post content blobs (`the_content` filter), but also for widget content blobs (`widget_text_content` and `widget_block_content` filters).

As part of the change, the `wp_img_tag_add_decoding_attr()` function has been deprecated. The filter of the same name continues to be maintained for backward compatibility, as before covering only images that are part of a content blob such as post content (`the_content`).

The `wp_get_loading_optimization_attributes()` function, which was introduced in 6.3, based on the now deprecated `wp_get_loading_attr_default()` function introduced in 5.5, relies on a `$context` parameter based on which it may alter its behavior and the attributes returned. So far, it has only supported context values used within WordPress core.
This changeset decouples the behaviors of the function from specific contexts, allowing for more flexibility. Theme and plugin developers will be able to rely on their own context values when rendering images in non-standard ways, rather than being forced to use a core context, to get the loading optimization benefits the function provides.
As part of this change, a `wp_loading_optimization_force_header_contexts` filter is introduced, which allows filtering the map of context values and whether they should be considered header contexts, i.e. i.e. any image having one of these contexts will be assumed to appear above the fold.

While the `wp_get_loading_optimization_attributes()` function was only recently introduced in 6.3, its code was mostly ported over from the now deprecated `wp_get_loading_attr_default()` function introduced in 5.5.
That function started out in a simple way, but over time was expanded with more and more conditionals on when to avoid lazy-loading, which ended up making the logic extremely complex and hard to follow.
This changeset refactors the logic to simplify it, in a way that allows to follow it more sequentially, and without making any functional changes, ensuring that the extensive existing unit test coverage still passes. This will facilitate future enhancements to the function to be less error-prone and make it more accessible to new contributors.
