Introduces the `wp_interactivity_get_element()` function to the Interactivity API, analogous to the `getElement()` function in the `@wordpress/interactivity` JavaScript module. This function allows access to the current element being processed during directive processing.
The function returns an array containing the `attributes` property, which includes only the originally defined attributes present on the element. Attributes added or modified by directive processing are not included. This is intended for use in derived state properties inside `wp_interactivity_state()`, similar to how `wp_interactivity_get_context()` is used.
Example usage:
```php
wp_interactivity_state( 'myPlugin', array(
'buttonText' => function() {
$context = wp_interactivity_get_context();
$element = wp_interactivity_get_element();
return isset( $context['buttonText'] )
? $context['buttonText']
: $element['attributes']['data-default-button-text'];
},
) );
```
Includes unit tests to cover the new functionality.

The Interactivity API has a concept of "derived state" but it only worked on the client (JavaScript). This is the implementation that mirrors it, so derived state has good server-side solution.

Integrates the directives processing into the WP_Block class. It removes the overhead of running additional hooks when rendering blocks and simplifies the way we detect whether the directive processing should run on an interactive region of the produced final HTML for the blocks.
Introduces `interactivity_process_directives` filter to offer a way to opt out from directives processing. It's needed in Gutenberg: https://github.com/WordPress/gutenberg/pull/62095.

Use a priority of 100 to ensure that other filters can add additional directives before the processing starts.
This way, directives will be processed even if the `$parsed_block` variable is edited by a filter.

Increases clarity about where the function belongs to, bringing it in line with other related functions.
After initially merging this change in [57742] and reverting it in [57743], this reintroduces it now that the Gutenberg packages have been updated accordingly in [57760].
