Add missing doc blocks to `update.php`: 

* `wp_version_check()`, `wp_update_plugins()`, and `wp_update_themes()` do not return meaningful responses, and their responses are never handled by core. As such, they shouldn't alternately return `void` or `false`. "Returning" in those functions is just "bailing"
* In the same functions, `version.php` doesn't need to load if `WP_INSTALLING` is defined - the function will immediately bail, the values will never be read, and the globals won't be reset. I have unified the approach in all 3 functions.
* When returning filtered `$locale`, there is no need to set the variable twice.
* In `_maybe_update_core()`, `isset()` can take multiple values to bail before the call to `time()`, if necessary. This is a micro-optimization to prevent PHP from hitting the OS unnecessarily.

See #32444.
