Replace infinitely autoloading behavior on scroll with a user-controlled load more button. Fix a long standing accessibility issue in the media library. Infinite scroll poses a wide range of problems for accessibility, usability, and performance.
This change modifies the library to load 40 items in the initial view, with a load more button to load the next 40 items and a button to move focus from the load more region to the first of the most recently added items.
The text for communicating the jump target was broadly discussed, agreeing that the text incorporated here would most concisely and clearly convey the purpose of the button, and any further detail is learnable from use.

* Correct the `$filename` parameter type in `wp_get_webp_info()`.
* Use a consistent message when skipping tests due to the lack of WebP support.
* Remove unnecessary `else` branches after `markTestSkipped()`.
* Replace `assertEquals()` with more appropriate assertions.

Add support for uploading, editing and saving WebP images when supported by the server.
Add 'image/webp' to supported mime types. Correctly identify WebP images and sizes even when PHP doesn't support WebP. Resize uploaded WebP files (when supported) and use for front end markup.

Improve the check for sourceless or dimensionless media when determining if the lazy loading attribute should be added to iframes and images. Never include the lazy loading attribute on embeds of WordPress posts as the iframe is initially hidden.
Including `loading="lazy"` on initially hidden iframes and images can prevent the media from loading in some browsers.

In the wrapper function `wp_getimagesize()` check if the second parameter was passed before sending it to the PHP function `getimagesize()`.
The PHP function has a different execution path depending on the number of parameters passed, this ensures the wrapper function follows the appropriate path.

With changes that were introduced in [49889] the second parameter for getimagesize() function is expecting a a reference.
Previously, most calls did not pass the 2nd param, and as a result, we are getting unexpected results.
This was only a problem with applications that are using a custom stream wrapper, and the image contained EXIF data.

Previously, all logic utilizing `getimagesize()` was supressing errors making it difficult to debug usage of the function.
A new `wp_getimagesize()` function has been added to allow the errors to no longer be suppressed when `WP_DEBUG` is enabled.

* Expands the capabilities of `wp_filter_content_tags()` to add the attribute to iframe tags if enabled.
* Modifies the default behavior of `wp_lazy_loading_enabled()` so that it returns `true` for `iframe` tags.
* Introduces a `wp_iframe_tag_add_loading_attr()` function.
* Introduces a `wp_iframe_tag_add_loading_attr` filter.
Like for images, the attribute is only added to iframes which have both `width` and `height` specified (see related #50367).

Using the canonical function name for PHP functions is strongly recommended, as aliases may be deprecated or removed without (much) warning.
This replaces all uses of the following:
* `join()` with `implode()`
* `sizeof()` with `count()`
* `is_writeable()` with `is_writable()`
* `doubleval()` with a `(float)` cast
In part, this is a follow-up to #47746.
