drm/amd/display: Cover crtc vblank restore replay-supported path

Browse source

Add dm_test_crtc_enable_vblank_ips_restore_replay to cover the
pr->config.replay_supported side of the sr_supported OR in
amdgpu_dm_crtc_set_vblank().

The existing IPS restore test establishes self-refresh support via the PSR
version. This test instead marks the PSR version unsupported and sets
replay_supported, forcing the sr_supported computation to fall through to
the replay branch while still calling drm_crtc_vblank_restore().
