gpu: nvgpu: scheduler management uapi

Browse Source 
Add ioctls for creating, removing and querying scheduling domains and
interface with the "nvsched" entity that will be the core scheduler.
Include the scheduler in the Linux build.

The core scheduler code will ultimately hold data on and control what
gets scheduled, but this intermediate layer in nvgpu-rm needs a bit of
bookeeping to manage the userspace interface.

To keep changes isolated, this does not touch the internal runlist
domains yet. The core scheduler logic will eventually control the
runlist domains.
