 Tests: Cover Block Hooks integration with a custom block theme

 Adds a simplified version of Twenty Twenty-Three theme that helps testing
 Block Hooks integration. The theme contains:

 - The required index.html template.
 - The optional single.html template used with tests.
 - 3 template parts where two of them reference patterns.
 - 3 patterns referenced in the templates and the template parts.

 New tests automatically register 4 custom blocks with the test theme where
 each of them hooks into another block using all four target relative
 positions: `before`, `after`, `firstChild`, `lastChild`.

 The tests verify that the block gets hooked into the correct positions
 when targeting:

 - template
 - template part
 - pattern

 Props ockham, costdev.
 See #59313, #59383.
