rhi: Expose device name, type, and IDs

...to the extent it is sensible. We have to make compromises still,
meaning some fields will only be applicable with certain APIs.

Most of this is already shown upon QRhi::create() as info debug
prints, when enabled. Now expose it all through the QRhi API as
well.

This is useful for printing in qtdiag, and, while it should be
avoided as much as possible, to make decisions about disabling
3D rendering features depending on the driver and GPU in use.
