vo_gpu_next: don't force PQ output for SDR sources if target is unknown

Browse Source 
We currently force PQ output when target_csp() is not available, to
preserve compatibility with backends that do not support it and to
enable HDR on them. However, for SDR transfers we can safely skip this
and simply use the source mode instead.

Ultimately, this "force PQ" mode needs to be removed, but target_csp()
is still not implemented for all relevant backends.
