Editor: Update block-serialization-default-parser package for WP 6.3 Beta 1.

Update the @wordpress/block-serialization-default-parser to 4.35.1 for WordPress 6.3 Beta 1. These changes split the following classes in to their own files in order to match the WordPress PHP coding standards:

• WP_Block_Parser_Block
• WP_Block_Parser_Frame
• WP_Block_Parser

These classes were previously all included in the src/wp-includes/class-wp-block-parser.php file. In order to maintain backward compatibly for developers requiring the file directly, the relocated classes are replaced with require_once calls in the original file.

In order to retain the commit history of the new files, they have been created using the svn copy command.
