Subject: [PATCH] Editor: Separate content styles for iframe in
 __wp_get_iframed_editor_assets() and wp_default_styles().

This changeset:
* Removes the `'wp-block-editor'` and `'wp-block-library'` from the iframe's stylesheet collection (i.e. `_wp_get_iframed_editor_assets()`).
* Adds the new `'wp-block-editor-content'` for the separate stylesheet to the list of editor (`'wp-edit-blocks'`) dependencies.

Why?

These PHP changes are part of the initiative to:

* Separate the content styles contained in the block editor package into a separate stylesheet.
* Avoid loading all block editor styles into the iframe.

References:
* [https://github.com/WordPress/gutenberg/pull/44298 Gutenberg PR 44298].

Follow-up to [53160], [50761].

Props ellatrix, youknowriad.
Fixes #57550.
