In PHP 8, the GD extension uses `GdImage` objects instead of resources for its underlying data structures.
This updates the existing `is_resource()` calls for image resources in core to accomodate for `GdImage` instances as well.

- Introduce `wp_image_file_matches_image_meta()` utility function to check whether the image meta (retrieved by attachment ID) matches an image path or URI. A mismatch may happen in some cases, for example after the posts have been exported from one website and imported in another.
- Add unit tests for the new function.
- Improve `wp_image_src_get_dimensions()` a bit and use the new function to prevent these edge cases.

With this changeset, in addition to the already present `wp_lazy_loading_enabled` filter, developers can now opt out of lazy-loading template images via `wp_get_attachment_image()` by passing a `loading` attribute with boolean value `false`. This can be used e.g. by theme developers on images which are very likely to be in the initial viewport.
This changeset also improves related test coverage.

Following up on [48170], this changeset moves the new logic to add missing `img` dimension attributes into a separate function that is run first within `wp_filter_content_tags()`. It also adds a utility function `wp_image_src_get_dimensions()` with logic reused from `wp_image_add_srcset_and_sizes()`, and it ensures that `width` and `height` attributes only get added if both of the attributes are missing on the original `img` tag.
This changeset furthermore improves test coverage and separates tests for the different aspects of `img` tag modification.

The filter is the callback function added with `add_filter()`, therefore the hook passes a value to the filter, and the filter returns a value to change its behaviour.
The documentation is referring to the latter.

This changeset ensures that attachment images which are inserted without `width` and `height` attributes still receive them in the frontend, to reduce cumulative layout shift. Adding the dimensions happens as part of the logic for adding `srcset` and `sizes` attributes, which already assume the specific width and height of the respective image.
Images are now only lazy-loaded if they have `width` and `height` attributes present. While missing these attributes itself is what causes layout shifts, lazy-loading such images can make this problem more apparent to the user.

The tag was supported in phpDocumentor 1.x, but is no longer supported in 2.x and 3.x.
Usage of static variables is considered an internal implementation detail and has no information value for someone reading the docs.

The array returned by this function previously included a fourth element only when an intermediate image size was used. This change ensures a consistent structure in the returned array regardless of the function's internal behaviour.

Visible `<label>` elements benefit all users. The `placeholder` attribute should not be used as a replacement for visible labels.
Instead, it's supposed to be used only for a short hint to aid users with data entry e.g. a sample value or a brief description of the expected format.
Screen readers may not announce a `placeholder` attribute at all. Other users may suffer from the lack of a visible label and a placeholder used as replacement, for example:
- users with cognitive disabilities may have trouble remembering what the filled field does
- speech recognition users cannot see the name they can speak to set focus on the field
- low-vision users with high text-size may not be able to see the whole placeholder even when it's visible, if its value is clipped by the edge of the input

Headings are the predominant mechanism for screen reader users to find information in a page. They also help all users to better identify the main sections of user interfaces.
