Subject: [PATCH] Themes: Use instanceof in get_hooked_blocks.

In [56610], the get_hooked_blocks function was introduced. However, using property_exists within this function negatively impacted its performance. This commit replaces the property_exists function call with instanceof WP_Block_Type, resulting in improved performance.

Props gziolo, spacedmonkey.
See #59383.
