New NVDEC and VIC implementation (#1384)
* Initial NVDEC and VIC implementation
* Update FFmpeg.AutoGen to 4.3.0
* Add nvdec dependencies for Windows
* Unify some VP9 structures
* Rename VP9 structure fields
* Improvements to Video API
* XML docs for Common.Memory
* Remove now unused or redundant overloads from MemoryAccessor
* NVDEC UV surface read/write scalar paths
* Add FIXME comments about hacky things/stuff that will need to be fixed in the future
* Cleaned up VP9 memory allocation
* Remove some debug logs
* Rename some VP9 structs
* Remove unused struct
* No need to compile Ryujinx.Graphics.Host1x with unsafe anymore
* Name AsyncWorkQueue threads to make debugging easier
* Make Vp9PictureInfo a ref struct
* LayoutConverter no longer needs the depth argument (broken by rebase)
* Pooling of VP9 buffers, plus fix a memory leak on VP9
* Really wish VS could rename projects properly...
* Address feedback
* Remove using
* Catch OperationCanceledException
* Add licensing informations
* Add THIRDPARTY.md to release too
