 In [changeset:"56044" 56044]:
 {{{
 #!CommitTicketReference repository="" revision="56044"
 Editor: Register core block styles in one place.

 Register all core blocks in a new function called
 `register_core_block_style_handles`. This mirrors the function
 `wp_default_styles` where all core styles are registered in one place.
 This improves block registration performance, as it avoids expensive file
 lookups, like realpath in `register_block_style_handle`. The new function
 `register_core_block_style_handles` uses `glob` to get all css files in
 the blocks directory. This glob is cached in a transient to save lookups
 on subsequent requests. The function `register_block_style_handle` now
 checks to see if the style handle is already registered before trying to
 register it again.

 Fixes #58528.
