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.

The Tag Processor stores the byte-offsets into its HTML document where
the current token starts and ends, and also for every bookmark. In some
cases for tags, the end offset has been off by one.
In this patch the offset is fixed so that a bookmark always properly
refers to the full span of the token it's bookmarking. Also the current
token byte offsets are properly recorded.
While this is a defect in the Tag Processor, it hasn't been exposed
through the public interface and has not affected any of the working
of the processor. Only subclasses which rely on the length of a bookmark
have been potentially affected, and these are not supported environments
in the ongoing work.
This fix is important for future work and for ensuring that subclasses
performing custom behaviors remain as reliable as the public interface.

The Interactivity API has been rendering client data in a SCRIPT element with the
type `application/json` so that it's not executed as a script, but is available
to one. The data runs through `wp_json_encode()` and is encoded with some flags
to ensure that potentially-dangerous characters are escaped.
However, this can lead to some challenges. Eagerly escaping when not necessary
can make the data difficult to comprehend when reading the output HTML. For example,
all non-ASCII Unicode characters are escaped with their code point equivalent.
This results in `\ud83c\udd70` instead of `🅰`.
In this patch, the flags for JSON encoding are refined to ensure what's necessary
while relaxing other rules (leaving in those Unicode characters if the blog charset
is UTF-8). This makes for Interactivity API data that's quicker as a human reader
to decipher and diagnose.
In summary:
- This data is JSON encoded and printed in a `<script type="application/json">` tag.
- If we ensure that `<` is never printed inside the data, it should be impossible to
break out of the script tag and the browser treats everything as the element's `textContent`.
- All other escaping becomes unnecessary at that point, including unicode escaping
if the page uses the UTF-8 charset (the same encoding as JSON).

Interactivity API has hooks that run on the frontend, but not in wp-admin. This means that interactivity data was not printed to the HTML and the interactivity Script Modules were not registered.

This prunes stores and configurations that are empty arrays, as stores are expected to be JSON objects.
By not printing empty configurations, less redundant data is serialized into the HTML.

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.

Short-circuits directive processing when the markup does not actually contain any `data-wp-*` attributes.
This reduces function calls and memory usage for the best case scenario due to not involving `WP_HTML_Tag_Processor`.

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].
