Comment:

 In [changeset:"56805" 56805]:
 {{{
 #!CommitTicketReference repository="" revision="56805"
 Blocks: Call `get_hooked_blocks` only once per template/part/pattern.

 Prior to this changeset, `get_hooked_blocks` was called four times ''for
 every parsed block'' in each template, template part, and pattern. With
 this changeset applied, `get_hooked_blocks` is called only once per
 template, template part, or pattern.

 Additionally, `get_hooked_blocks` is called only once when returning the
 list of all registered patterns. (The latter modification brings the
 implementation closer to its state prior to Block Hooks.)

 Finally, when there are no registered hooked blocks or
 `hooked_block_types` filters, parsing, hooked block insertion, and re-
 serializing is skipped altogether.

 Props gziolo, flixos90, joemcgill, dmsnell, spacedmonkey, hellofromtonya.
 Fixes #59383.
