When a post type is passed to `get_block_templates()` in the query, return only the templates that match that post type.
Fixes an issue where:
* when a block template provided by a theme has been edited by the user
* and that template has specific defined `postTypes`
* but after editing, the template was available for all post types.

Block Themes should now use the following folders:
- templates instead of block-templates
- parts instead of block-template-parts
Existing themes and folders will continue to work without impact.
