UI: Use CQP for NVENC when using simple output mode

Browse Source 
When using simple output mode, previously NVENC did not support a
constant quality rate control method, and you'd have to use VBR with
bitrate.  However CQP has since been added to NVENC, and it's preferable
to use for recording when available instead of using VBR.
