REST API: Synchronize permission checks in ::get_items_permissions_check() methods for post types, post statuses, and users:

Browse Source 
* Only query post types with `'show_in_rest' => true` instead of looping over all post types and checking the `show_in_rest` property separately.
* Return from the `foreach()` loop as soon as the permission check succeeded.

Props pbiron, TimothyBlynJacobs, SergeyBiryukov.
Fixes #49118.
