[RFC 0/2] drm: fdinfo memory stats

Similar motivation to other similar recent attempt[1]. But with an
attempt to have some shared code for this. As well as documentation.

It is probably a bit UMA-centric, I guess devices with VRAM might want
some placement stats as well. But this seems like a reasonable start.

TODO gputop support?
