Editor: Improve block loading PHP performance.

This commit improves PHP performance for core blocks by reading a single PHP file with block metadata, instead of reading a JSON file per-block and then decoding from JSON to PHP.

Includes:
* Adding a new Grunt task to convert `block.json` files to `block-json.php`.
* Using the new `block-json.php` file in the `register_block_type_from_metadata()` function.

Follow-up to [48141].
