Thinking about this some more, I think what I'm really after is just a
generic way for an app to request a vendor-defined report from a
controller, so that libraries like SDL can better request the
capabilities of a device when trying to handle devices properly. As it
stands, PS4, PS5, OG Xbox, Xbox 360 and Xbox One all have vendor
defined reports that can be fetched for describing controller
information, but only PS4 and PS5 actually even give something like
SDL the ability to fetch that data right now because they can just do
hid feature report reads to get it, while the Xbox controllers don't
use HID and thus we need to expose that from the input layer.
