Comment:

 In [changeset:"55138" 55138]:
 {{{
 #!CommitTicketReference repository="" revision="55138"
 Themes: Add static cache variable to wp_theme_has_theme_json().

 For performance, a static variable is added to `wp_theme_has_theme_json()`
 to cache the boolean result of determining if a theme (or its parent) has
 a `theme.json` file.

 This cache avoids the overhead of calling `get_stylesheet_directory()` and
 `get_template_directory()` each time `wp_theme_has_theme_json()` is
 invoked.

 The cache is lean, non-persistent, and encapsulated within the function
 (i.e. function scope and not available externally).

 The cache is ignored when:
 * `WP_DEBUG` is on to avoid interrupting theme developer's workflow and
 for extender automated test suites.
 * `WP_RUN_CORE_TESTS` is on to ensure each Core test exercises the
 checking code.

 Follow-up to [55092], [55086].

 Props oandregal, azaozz, costdev, dmsnell, flixos90, hellofromTonya,

 Fixes #56975.
