drm_hwcomposer: Remove GL compositing support

The GL based compositing adds alot of complexity and was only ever well
tested on closed stacks. It also only supports GLES3.x and still relies
on sw_sync timeline which is now a debugfs feature. Those are just the
known issues.

Removing the GL compositor means everything related to squashing layers
and pre-compositing can be removed. The planner is left as it may be
useful when adding back support for overlay planes. With this change,
only a single plane is supported until ValidateDisplay learns to do
atomic modesetting test for overlay planes.
