Detects Android MediaCodec FFmpeg decoders for H.264/VP8/VP9 when NVDEC GPU decoding is selected.
Required proper support of ffmpeg extradata, h264 frame dimensions and decoder frame handling.
Reenabled (uncommented) NVDEC Emulation selector on Android interface.

- fix va-api not being used on freebsd
small thingies dont affect a lot:
- removes some pointer indirection (why save pointer to GMMU if its accesible via host1x)
- use std::variant<> for decoder
- miscelly vp9/v8/h264 opts

This commit aims to implement the NVDEC (Nvidia Decoder) functionality, with video frame decoding being handled by the FFmpeg library.
The process begins with Ioctl commands being sent to the NVDEC and VIC (Video Image Composer) emulated devices. These allocate the necessary GPU buffers for the frame data, along with providing information on the incoming video data. A Submit command then signals the GPU to process and decode the frame data.
To decode the frame, the respective codec's header must be manually composed from the information provided by NVDEC, then sent with the raw frame data to the ffmpeg library.
Currently, H264 and VP9 are supported, with VP9 having some minor artifacting issues related mainly to the reference frame composition in its uncompressed header.
Async GPU is not properly implemented at the moment.
