drm/amd/display: Refactor SDR cursor boosting in HDR mode
...
[Why]
Cursor boosting is done via CNVC_CUR register which is DPP, not HUBP
Previous commit was implementing it in HUBP functions,
and also breaking diags tests.
[How]
1. Undo original commit as well as Eric's diags test fix, almost completely
2. Move programming to DPP and call via new dc_stream function
3. Also removing cur_rom_en from dpp_cursor_attributes and programming
as part of normal cursor attributes as it depends on cursor color format

[how]

drm/amd/display: Clear underflow status for debug purposes
...
We want to keep underflow sticky bit on for the longevity tests outside
of test environment. For debug purposes it is, however, useful to clear
underflow status after the test that caused it so that the following
tests are not affected. This change fullfils both requirements by clearing
the underflow only from within Windows or Diags test environment.
