Implement a mock scheduler backend and add some basic test to exercise the core scheduler code paths. Mock backend (kind of like a very simple mock GPU) can either process jobs by tests manually advancing the "timeline" job at a time, or alternatively jobs can be configured with a time duration in which case they get completed asynchronously from the unit test code. Core scheduler classes are subclassed to support this mock implementation. The tests added are just a few simple submission patterns.

Use dynamic-debug to avoid drm_debug_enabled() runtime overheads.

Due to callsite counts in DRM drivers (~4k in amdgpu) and 56

bytes per callsite, the .data costs can be substantial, and

are therefore configurable.

A kernel build should not cause any compiler warnings, and this

enables the '-Werror' flag to enforce that rule in the drm subsystem.

The drm subsystem enables more warnings than the kernel default, so

this config option is disabled by default.
