 General: Introduce `WP_DEVELOPMENT_MODE` constant to signify context-
 specific development mode.

 In recent releases, WordPress core added several instances of cache usage
 around specific files. While those caches are safe to use in a production
 context, in development certain nuances apply for whether or not those
 caches make sense to use. Initially, `WP_DEBUG` was used as a temporary
 workaround, but it was clear that a more granular method to signify a
 specific development mode was required: For example, caches around
 `theme.json` should be disabled when working on a theme as otherwise it
 would disrupt the theme developer's workflow, but when working on a plugin
 or WordPress core, this consideration does not apply.

 This changeset introduces a `WP_DEVELOPMENT_MODE` constant which, for now,
 can be set to either "core", "plugin", "theme", or an empty string, the
 latter of which means no development mode, which is also the default. A
 new function `wp_get_development_mode()` is the recommended way to
 retrieve that configuration value.

 With the new function available, this changeset replaces all existing
 instances of the aforementioned `WP_DEBUG` workaround to use
 `wp_get_development_mode()` with a more specific check.

 Fixes #57487.
