drm/amd/display: Move backlight macros to backlight header

Browse source

[WHAT]
Move AMDGPU_DM_DEFAULT_MIN_BACKLIGHT, AMDGPU_DM_DEFAULT_MAX_BACKLIGHT,
AMDGPU_DM_MIN_SPREAD, and AUX_BL_DEFAULT_TRANSITION_TIME_MS from
amdgpu_dm_backlight.c to amdgpu_dm_backlight.h so they can be reused
by KUnit tests. Update the test file to use these macros instead of
hardcoded literal values.
