Add QVideoFrame::Format_NV12 (AVFoundation has kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange
and kCVPixelFormatType_420YpCbCr8BiPlanarFullRange). Report it (set it) only if
it's supported by renderer's surface. Add bi-planar format support into CVPixelBufferVideoBuffer.

The non-OS X path also uses clGetGLContextInfoKHR when available,
instead of just blindly taking the first GPU device for the platform.
This way we get the correct OpenCL device in case the application is using an
OpenGL context on the same vendor's second GPU.
On Windows desktop OpenGL is now correctly forced and therefore there is
no need to waste time on runtime checks for ANGLE later on.
Remove the hard-coded custom pathes from the .pro file.
Also fixes error reporting on the OS X specific path.

This reverts commit 0ab81ef59f.
The workaround causes software devices not to appear in the list

in older versions of Alsa, the workaround was probably a bad idea
in the first place. People should update Alsa instead.

Excluding video range (iOS) is not the right way to avoid "duplicates" - with
other devices there can be also duplicates (formats with the same resolutions),
but completely different pixel formats. Since we do not know what they will be in advance,
we take the media subtype from the initial preset for a capture device and use it
as a filter. Update viewfinder and image encoder settings controls.

That's because in that particular situation, the backend believed
the delayed loading was a reload of the same media.

640x480 (ratio=1.3333).
