Make layout support compatible with enhanced pagination by ensuring that generated class names are stable across pagination, even when the number of rendered posts is different.
With the previous implementation of enhanced pagination, the CSS corresponding to each block was not detected. Therefore, for enhanced pagination to work correctly, the CSS of the blocks present in the Post Template must be stable on all pages.
The number of posts rendered by the Query block is always the same, except in the last page, where it can be only a fraction. If any of the blocks rendered by the Post Template used the `wp_unique_id` function, the ID (which is incremental) would have been different than in the previous pages and the class names would have varied.
This is remediated by this changeset by replacing the usage of `wp_unique_id` in the layout support (which is used by the Query block) with an implementation that uses IDs that are incremental only for that block. That way, the generated class names are never affected by the number of times `wp_unique_id` runs.

By skipping iterations in block supports when not necessary, this changeset improves performance of the function notably.
The performance enhancement leads to even a notable improvement for overall page load time: For example, the Twenty Twenty-Four home page loads ~2% faster with this changeset.

`_wp_array_get()` is an expensive function, and it's called thousands of times on each page view on the front end. While the function performance was slightly improved in #58376, it is still called more times than it should be.
This commit aims to further optimize its usage:
* In many cases, `_wp_array_get()` can be replaced with a much simpler and faster `isset()` check.
* The `isset()` function is capable of checking nested arrays, so `isset( $foo['a']['b']['c'] )` will return false even if `$foo['a']` is unset, without throwing any errors or warnings.
* When `_wp_array_get()` cannot be directly replaced with `isset()`, it would be good practice to wrap it in an `isset()` function so that `_wp_array_get()` only runs when it needs to.

Most block feature checks are for a single feature string, and for such cases it is not intuitive to require an array for the `$feature` parameter of the `block_has_support()` function.
This changeset brings it in line with other functions like `post_type_supports()`, allowing to pass a string for the `$feature`. An array is still supported for more complex cases where support for sub-features needs to be determined. This change furthermore includes a very minor performance tweak by avoiding calls to the `_wp_array_get()` function if a single feature string is being checked for.

Introduced in [56101] the `WP_Duotone` class, hooks into the `wp_loaded` action to load duotone style data from global styles. Hooking in early in the bootstrap process caused a number of problems. This hook, triggered an error on installing, as this lookup for global styles, would result in a global post trying to be created, even before the table existed. Additionally, this implementation caused a severe performance regression, as duotone styling data was loaded unnecessarily for requests that did not require such data, such as REST API calls or actions within the wp-admin interface.
In this change, refactor the `WP_Duotone` to lazily load the global styles and theme.json data, only when a block that supports duotone is encountered. The method `render_duotone_support` was change to take a third parameter to reuse the existing `WP_Block_Type` object passed to the filter, to save it being looked up again. The code has also got improved type checking and the use of the util function `block_has_support`. Furthermore, the code's readability has been improved, along with enhancements to the documentation blocks.

`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).
WordPress core includes a polyfill for `str_contains()` on PHP < 8.0 as of WordPress 5.9.
This commit replaces `false !== strpos( ... )` with `str_contains()` in core files, making the code more readable and consistent, as well as better aligned with modern development practices.

[55230] introduced a regression to the content markup. This changeset is a partial revert to remove the added `wp-includes/block-supports/anchor.php` file.
The change of adding `'id'` to `$attributes_to_merge` in `get_block_wrapper_attributes()` is not reverted as this change did not impact the regression and helps to support continue development in Gutenberg for the anchor support in dynamic blocks feature.
