Posts: Allow the list of wrapper blocks to be filtered.

This introduces the `excerpt_allowed_wrapper_blocks` filter for controlling which blocks should be considered wrapper blocks.

Wrapper blocks and their nested contents are not stripped by `excerpt_remove_blocks()`, allowing their contents to appear in generated excerpts.

Follow up to [51348].

Props aristath, jorbin.
See #53604.
