Backports PHP changes in WordPress/gutenberg#41791 to the core. Adding the post types property to the rest API.

Testing

Added the following code snippet:

register_block_pattern( 'custom-pattern', array(
			'title'      => _x( 'Start post pattern', 'Block pattern title', 'gutenberg' ),
			'blockTypes' => array( 'core/paragraph', 'core/post-content' ),
			'postTypes' => array( 'post' ),
			'content'    => '<!-- wp:paragraph -->
<p>A start post pattern</p>
<!-- /wp:paragraph -->',
		) );

Opened the editor pasted on the browser console:

wp.apiFetch( { path: '/wp/v2/block-patterns/patterns' } ).then( console.log );

Verified post types was included in the rest response as part of custom-pattern.
