Sergey Biryukov 49401759f3 Docs: Correct `@param` type for the function parameter in `tests_add_filter()` and `_test_filter_build_unique_id()`. 
Synchronize documentation for `add_filter()`, `tests_add_filter()`, `_wp_filter_build_unique_id()`, `_test_filter_build_unique_id()`.

Add a note that `$tag` and `$priority` are no longer used in `_wp_filter_build_unique_id()` since [46220], and the function always returns a string now.

Sergey Biryukov acd0a3ca99 Site Health: Add a test for PHP default timezone. 
The test reports a failure if the default timezone was changed with `date_default_timezone_set()` to anything other than `UTC`.

WordPress historically uses `UTC` as the default timezone for calculating date and time offsets, overriding it is not recommended and can cause widespread and obscure issues.
