Deprecate `AbstractController::Callbacks#skip_action_callback`

As part of #19029, in future `skip_before_action`, `skip_after_action` and
`skip_around_action` will raise an ArgumentError if the specified
callback does not exist. `skip_action_callback` calls all three of these
methods and will almost certainly result in an ArgumentError. If anyone
wants to remove all three callbacks then they can still call the three
individual methods. Therefore let's deprecate `skip_action_callback` now
and remove it when #19029 is merged.

 *   Alias the `ActionDispatch::Request#uuid` method to `ActionDispatch::Request#request_id`.
     Due to implementation, `config.log_tags = [:request_id]` also works in substitute
     for `config.log_tags = [:uuid]`.
