drm/amd/display: add check in validate_only in dml2

Browse source

[what]
does_configuration_meet_sw_policies check was not done in the
validate_only portion of dml2, so some unsupported modes were passing bw
validation, only to fail the same check later in validate_and_build. now
we add the check to validate_only.

Also add line in dcn35_resource to ensure that value set for
enable_windowed_mpo_odm gets passed to dml.

[why]
Immediate black screen during video playback at 4k144hz. The debugger
showed that we were failing validation in dml on every updateplanes().
