Message:

Block Hooks: Allow child insertion into Template Part block.

The Block Hooks mechanism was previously extended to allow insertion of a block as a Navigation block's first or last child. This was implemented by storing the ignoredHookedBlocks array in the corresponding wp_navigation post's post meta (instead of a metadata attribute on the anchor block).

This changeset extends that mechanism to Template Part blocks, by storing said metadata in the corresponding wp_template_part post's post meta, thus allowing extenders to use Block Hooks to insert a block as a Template Part block's first or last child, respectively.

Props tomjcafferkey, bernhard-reiter.
Fixes #60854.
