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
the attachment page.

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).

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.

`str_contains()` was introduced in PHP 8.0 to perform a case-sensitive check indicating if the string to search in (haystack) contains the given substring (needle).

Follow-up to [56037], as that changeset accidentally did not consider the changes made in [55825]: Images that are programmatically injected into post content (e.g. through a block, or shortcode, or any hook calling a function like `wp_get_attachment_image()`) must be treated as part of the whole post content blob since otherwise the heuristics for applying `fetchpriority="high"` and `loading="lazy"` are skewed by parsing certain images before others rather than sequentially parsing the entire post content. [55825] addressed that for lazy-loading, but when [56037] introduced `fetchpriority` support, the related refactor missed making the same consideration for that attribute.

Following [55318], [55847], and [56142], certain images in the header of the page have received support for potentially receiving `fetchpriority="high"` and having the `loading="lazy"` attribute omitted. However, these images being present did not affect the "content media count" which counts the images towards a certain threshold so that the first ones are not lazy-loaded.
This changeset also increases that count for such header images if they are larger than a certain threshold. The threshold is used to avoid e.g. a header with lots of small images such as icon graphics to skew the lazy-loading behavior.

This changeset adds support for the `fetchpriority` attribute, which is typically added to a single image in each HTML response with a value of "high". This enhances load time performance (also Largest Contentful Paint, or LCP) by telling the browser to prioritize this image for downloading even before the layout of the page has been computed. In lab tests, this has shown to improve LCP performance by ~10% on average.
Specifically, `fetchpriority="high"` is added to the first image that satisfies all of the following conditions:
* The image is not lazy-loaded, i.e. does not have `loading="lazy"`.
* The image does not already have a (conflicting) `fetchpriority` attribute.
* The size of of the image (i.e. width * height) is greater than 50,000 squarepixels.
While these heuristics are based on several field analyses, there will always be room for optimization. Sites can customize the squarepixel threshold using a new filter `wp_min_priority_img_pixels` which should return an integer for the value.
Since the logic for adding `fetchpriority="high"` is heavily intertwined with the logic for adding `loading="lazy"`, yet the features should work decoupled from each other, the majority of code changes in this changeset is refactoring of the existing lazy-loading logic to be reusable. For this purpose, a new function `wp_get_loading_optimization_attributes()` has been introduced which returns an associative array of performance-relevant attributes for a given HTML element. This function replaces `wp_get_loading_attr_default()`, which has been deprecated. As another result of that change, a new function `wp_img_tag_add_loading_optimization_attrs()` replaces the more specific `wp_img_tag_add_loading_attr()`, which has been deprecated as well.
See https://make.wordpress.org/core/2023/05/02/proposal-for-enhancing-lcp-image-performance-with-fetchpriority/ for the original proposal and additional context.
