Comment:

 In [changeset:"54415" 54415]:
 {{{
 #!CommitTicketReference repository="" revision="54415"
 Blocks: Avoid extra calls to `realpath()` in block scripts and styles
 registration.

 This affects:
 * `register_block_script_handle()`
 * `register_block_style_handle()`

 Both functions set a variable with this code:
 {{{
 $wpinc_path_norm = wp_normalize_path( realpath( ABSPATH . WPINC ) );
 }}}

 That value never changes during page load, so we can save it to a static
 variable. By doing so, we can avoid ~200 calls to `realpath()` and
 `wp_normalize_path()`, or even more if third-party plugins register
 scripts or styles.

 Follow-up to [52291], [52939], [54290], [54291], [54309], [54327].

 Props aristath, mukesh27, SergeyBiryukov.
 Fixes #56758.
