obs-qsv: Expose additional QSV encoder settings through GUI

Browse Source 
- Allow user to change # of B frames. New Default -> 1
- Allow user to enable Content Adaptive Quantization (MBBRC) if CPU is Skylake or newer.
- Allow user to choose LA_CBR as a rate control.
- LA depth: New Default -> 15, only when LA rate control is used.
