`str_starts_with()` was introduced in PHP 8.0 to perform a case-sensitive check indicating if the string to search in (haystack) begins with the given substring (needle).
WordPress core includes a polyfill for `str_starts_with()` on PHP < 8.0 as of WordPress 5.9.
This commit replaces `0 === strpos( ... )` with `str_starts_with()` in core files, making the code more readable and consistent, as well as improving performance.
While `strpos()` is slightly faster than the polyfill on PHP < 8.0, `str_starts_with()` is noticeably faster on PHP 8.0+, as it is optimized to avoid unnecessarily searching along the whole haystack if it does not find the needle.

Remove the `theme` parameter from the query passed to `get_block_templates()`. It is not used or documented. This removal doesn't have any effect in the code, as the data is ignored anyway.

The internal Core-only `_resolve_home_block_template()` function was introduced in [53093] for a specific purpose of resolving the template for a site's home page. It was used as part of the Site Editor's redirect when the `postType` and `postId` query args were missing. The server-side handling was removed in [55338]. The function is no longer used in Core.
This changeset deprecates the function and removes its tests.

[52065] originally introduced the logic to guess the LCP image based on certain heuristics and to not lazy-load that image. However, with the introduction of block themes, that logic was not functioning correctly, resulting in all featured images to be lazy-loaded, regardless of whether it was the LCP image or not.
Together with an update to the `core/post-featured-image` block included in [55079], this changeset fixes the logic to correctly handle featured images in block themes as well.
Additionally, in combination with an update to the `core/template-part` block from [55246], this changeset includes an enhancement which uses the benefits of block template parts to avoid lazy-loading images in the `header` block template part, making the lazy-loading heuristics even more accurate for sites using a block theme.

Calling the `wp_get_theme` function creates a instance of the `WP_Theme` class. This can be a performance issue, if all you need is one property of the class instance. This change replaces the usage of `wp_get_theme()->get_stylesheet()` with `get_stylesheet()` to improve performance.

[54248] reversed the wrapping of `do_shortcode` and `apply_shortcodes` and updated all direct internal calls of `do_shortcode` to `apply_shortcodes` after [47004]. After further consideration, the long history of `do_shortcodes` should be favored over any subjective semantic improvements. This change reverts the remaining changes from #55883 not already reverted in [54278].

This changeset reverses the wrapping of `apply_shortcodes()` and `do_shortcode()` such that `apply_shortcodes()` is now the recommended function. In addition:
- Calls to `do_shortcode()` have been changed to `apply_shortcodes()`.
- Some default filter callbacks have been changed from `'do_shortcode'` to `'apply_shortcodes'`.
- Applicable documentation has been updated to refer to `apply_shortcodes()` instead.

The template resolution system makes a request like `/?page_id=1234&_wp-find-template=true`, depending on `WP_Query` to resolve a page or post using the page_id or p (post_id) in the query string. With new posts/pages, a placeholder post with the status auto-draft is created. But by default `WP_Query` will not resolve these posts, unless the query is specifically set to look for them.
This commit handles the query string to properly resolve a page or post. It adds 2 private callbacks for the processing.

This change fixes template resolution to give precedence to child theme PHP templates over parent theme block templates with equal specificity.
Before this change, when a theme was using a PHP template of a certain specificity (e.g. `page-home.php`), and it happened to be a child theme of another theme which had a block template for the same specificity (e.g. `page-home.html`), WordPress was picking the parent theme’s block template over the child theme’s PHP template to render the page. If the PHP and block template have equal specificity, the child theme's template should be used.
The issue was fixed before in Gutenberg so the fix now needs to happen in Core.
This change also re-enables the preexisting template resolution unit tests.

I forgot this function existed.
And I thought that it would fatal, but it didn't
And it was so nice
So peaceful and quiet
