Only sysfb drivers use drm_fb_build_fourcc_list(). Move the function
to sysfb helpers and rename it accordingly. Update drivers and tests.
v3:
- update naming in tests
v2:
- select DRM_SYSFB_HELPER (kernel test robot)

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.

Move some options out into a new debug specific kconfig file in order to
make things a bit cleaner.
