This prevents a performance regression when a blocking script is enqueued in the footer which depends on a delayed script in the `head` (with `async` or `defer`). In order to preserve the execution order, a delayed dependency must fall back to blocking when there is a blocking dependent. But since it was originally delayed (and thus executes similarly to a footer script), it does not need to be in the head and can be moved to the footer. This prevents blocking the critical rendering path.

Using script tag helper functions allows plugins to employ the `wp_script_attributes` and `wp_inline_script_attributes` filters to inject the `nonce` attribute to apply Content Security Policy (e.g. Strict CSP). Use of helper functions also simplifies logic in `WP_Scripts`.
* Update `wp_get_inline_script_tag()` to wrap inline script in CDATA blocks for XHTML-compatibility when not using HTML5.
* Ensure the `type` attribute is printed first in `wp_get_inline_script_tag()` for back-compat.
* Wrap existing `<script>` tags in output buffering to retain IDE supports.
* In `wp_get_inline_script_tag()`, append the newline to `$javascript` before it is passed into the `wp_inline_script_attributes` filter so that the CSP hash can be computed properly.
* In `the_block_template_skip_link()`, opt to enqueue the inline script rather than print it.
* Add `ext-php` to `composer.json` under `suggest` as previously it was an undeclared dependency for running PHPUnit tests.
* Update tests to rely on `DOMDocument` to compare script markup, normalizing unsemantic differences.

This resolves a few WPCS warnings:
{{{

so that the output of `composer format` is clean.

This is a follow-up to [56092], which further improves PHPUnit test coverage and inline docs for ensuring `async` and `defer` attributes are being properly handled for scripts that are printed without being enqueued.

This allows developers to register scripts with an intended loading strategy by changing the `$in_footer` parameter of `wp_register_script` and `wp_enqueue_script` to an array that accepts both an `in_footer` and `strategy` argument. If present, the loading strategy attribute will be added to the script tag when that script is printed to the page as long as it is not a dependency of any blocking scripts, including any inline scripts attached to the script or any of its dependents.

`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.

The `$path` parameter of some script translation functions had a default value of `null`, even though the parameter is documented as a string.
This commit corrects the default value for `$path` in:
* `WP_Dependency::set_translations()`
* `WP_Scripts::set_translations()`
* `wp_set_script_translations()`
Additionally, this commit removes an `is_string()` check for `$path` in `load_script_textdomain()`. Now that the default value for `$path` in that function has also been corrected to an empty string instead of `null`, that check is no longer necessary, as it would ''hide'' an error which should be ''fixed'' (at the source of the problem) instead.

The current coding standards note that the name of the class files should be based on the class name with `class-` prepended, and the underscores replaced by hyphens (see the [https://developer.wordpress.org/coding-standards/wordpress-coding-standards/php/#naming-conventions Naming Conventions] section in the handbook), except for the three legacy files: `class.wp-dependencies.php`, `class.wp-scripts.php`, `class.wp-styles.php`.
To bring more consistency to the codebase and make it easier to implement autoloading in the future, this commit renames those three legacy files to conform to the coding standards:
* `wp-includes/class.wp-dependencies.php` → `wp-includes/class-wp-dependencies.php`
* `wp-includes/class.wp-scripts.php` → `wp-includes/class-wp-scripts.php`
* `wp-includes/class.wp-styles.php` → `wp-includes/class-wp-styles.php`
Includes:
* Loading the new files from the old ones, for anyone that may have been including the files directly.
* Replacing references to the old filenames with the new filenames.
