obs-qsv: Allow for multiple QSV encoders

Browse Source 
Allow multiple QSV encoders, usefull for live + recorded parallel
sessions.  The first QSV encoder will create a DirectX device and return
a handle / pointer.  Any additional QSV encoder will use that same
pointer to the DirectX device.  We keep track of the number of open
QSV encoders so that we wait to close the DirectX resources after all
encoders are closed.

Closes obsproject/obs-studio#1341
