 During profiling for TT3 home page, a performance bottleneck has been
 identified within the `register_block_type_from_metadata` function of the
 WordPress core. This function is responsible for a significant portion
 (approximately 8-10%) of the overall load time. Subsequent analysis
 reveals that the `register_block_script_handle` function, called within
 `register_block_type_from_metadata`, contributes to about 3% of the load
 time. Given these findings, there's a clear opportunity to enhance the
 performance of these functions.


 Within the `register_block_type_from_metadata` function, the
 `register_block_script_handle` function is being invoked four times. This
 is a significant contributor to the overall load time. Further examination
 of the code shows that the [https://github.com/WordPress/wordpress-
 develop/blob/trunk/src/wp-includes/blocks.php#L157 plugins_url function]
 is also called within this context. However, it appears that this call to
 "plugins_url" is relevant only for theme blocks.
