Implement DRM overlay composition
...
This allows overlays to work on drivers that only have one usable
overlay plane and when we are using the primary plane (which often
must be exactly CRTC-sized) to overlay on top of a video underlay.

This is currently race-prone because nothing is synchronizing

false negatives if we can't retake master ourselves.

Check modifiers support in IN_FORMATS property
...
As it turns out, there *are* in fact hardware vendors dumb enough
to ship V4L2 decoders that output buffers which are unsupported by
any plane on their display hardware. By checking modifiers, we can
still fall back to GLES on GL_IS_SLOW=1 builds in this case.

Remove async and non-blocking page flip support
...
It doesn't work well in practice for a few major reasons:
- It can result in the decoder writing on DMA-BUFs being used by the display
- It can generate page flip events that collide with Qt/SDL
- It can stall the decoder if the DMA-BUF has a fence on it from the display driver
