drm/amd/display: Expose target backlight level
[Why]
DM may want to understand any backlight optimizations
applied, so DM needs a way to query from the HW both
the real current backlight, which may be value during
transition.
And also target backlight, which may be after some
backlight optimizations applied.
[How]
Add interface to query current and target backlight levels
Target level may indicate backlight level after backlight
optimization and reductions are applied.
