Tests: Use `add_filter()` when it's available. 

The `tests_add_filter()` helper function directly manipulates the `$wp_filter` global, instead of using `add_filter()`. We can use `add_filter()` when it's available, and fall back to manipulating `$wp_filter` when it isn't, relying on the `$wp_filter` bootstrap code at the top of `plugin.php` to handle conversion.

Fixes #17817.
