Sergey Biryukov 3b4132d6c0 Build/Test Tools: Back up and restore the $wp_filters global when running tests.
Introduced along with the `did_filter()` function, the `$wp_filters` global stores the number of times each filter has been applied during the current request.

This commit adds `$wp_filters` to the list of globals that are saved in `WP_UnitTestCase_Base::_backup_hooks()` and restored in `::_restore_hooks()` so that hooks set by the current test do not accidentally affect future tests.

Additionally, this commit brings some consistency by backing up and restoring the hook-related globals in the same order they are defined in `wp-includes/plugin.php`.

Follow-up to [29251], [53803].

Props sanjucta, SergeyBiryukov.
Fixes #57236.
