drm/format-helper: Move drm_fb_build_fourcc_list() to sysfb helpers

Browse Source 
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)
