accidentally discarded

12eeffcb7c vp9: Be explicit with copy and move operators
It's deprecated in the language to autogenerate these if the destructor
for a type is specified, so we can explicitly specify how we want these
to be generated.

0d713cf8eb vp9: Mark functions with [[nodiscard]] where applicable
Prevents values from mistakenly being discarded in cases where it's a
bug to do so.

badea3b301 vp9: Provide a default initializer for "hidden" member
The API of VP9 exposes a WasFrameHidden() function which accesses this
member. Given the constructor previously didn't initialize this member,
it's a potential vector for an uninitialized read.

Instead, we can initialize this to a deterministic value to prevent that
from occurring.

f8543249f0 vp9: Make some member functions internally linked
These helper functions don't directly modify any member state and can be
hidden from view.

eb67a45ca8 video_core: NVDEC Implementation
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.
