lavc/videotoolbox: remove opengl compatability key

Browse Source 
We are not using OpenGL and this compatability key could introduce
performance penalty on some Macs. Performance difference is neglible
on Apple Silicon but on old Intel Macs like the 2018 MacBook Air,
decoding performance could be reduced by 15% as the IOSurface might
make extra frame copies to reshape the pixel buffer.
