Add schema support for FSE templates

[monbauza]

Moved from: https://yoast.atlassian.net/browse/PC-761 Reporter: @leonidasmi

Description

When we add blocks that add schema, in a FSE template, that isn’t considered when we output the frontend of a post of that template. Example:

• Go to the Site Editor and edit the Post template
• Add a Yoast How-to block in the Post template and save
• Create a post and check its schema
• In the schema no HowTo object is being output

We need to make sure we add support for that

Replicated both with WP 6.0.2 and 6.1 - with the Twenty Twenty-Two theme (which is a FSE theme)

Comment from Lars van Rhijn:

We need to adjust the get function in meta-tags-context-memoizer.php to also include the template blocks inside the $blocks variable. We might also need to change other schema generators that use the post content to generate their schema (such as faq.php).

There is only one problem, there is currently no nice way to request the template that is being rendered within WordPress. We might need to use resolve_block_template but this function is marked as private. We could also use $_wp_current_template_content but this global variable is also marked as being private.

Maybe introducing a filter to allow modifying the context/content can be a partial and temporary solution.
