 Previously, the `hooked_block_types` and
 `hooked_block_{$hooked_block_type}` filters were introduced to allow
 templates to be extended with blocks by third parties.

 While those two filters work well with unique blocks, they prove
 challenging when working with generic blocks that can be customized via
 attributes.  Attempting to hook a block into an area that has already
 inserted the same block type, but with different attributes won't work
 with the existing filters.

 [This PR](https://github.com/woocommerce/woocommerce/pull/44860)
 demonstrates how attempting to set attributes via the
 `hooked_block_{$hooked_block_type}` filter will overwrite all of the same
 block types that have been hooked in.


 It may be possible that block hooks aren't the appropriate venue for this
 API, but a way to insert blocks with attributes into templates is quite
 useful, even in the context of the core editor.

 **Requirements:
 **

 * [ ] Allow insertion of blocks with block attributes in a single filter
 * [ ] Allow checking anchor block properties before inserting hooked
 blocks
 * [ ] (optional, but preferred) Allow nesting hooked blocks onto previous
 hooked blocks
