Instead of using a two step initialization to report errors, initialize
the GPU renderer and rasterizer on the constructor and report errors
through std::runtime_error.
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.

Renames some variables to prevent ones in inner scopes from shadowing
outer-scoped variables.
The Copy* functions have no shadowing, but we rename them anyways to
remain consistent with the other functions.
This PR aims to reduce the memory usage in the CPU page table by moving
GPU specific parameters into a child class. This saves 1Gb of Memory for
most games.
Makes the class less surprising when it comes to forward declaring the
type, and also prevents inlining the destruction code of the class,
given it contains non-trivial types.
These are able to be omitted from the declaration of functions, since
they don't do anything at the type system level. The definitions of the
functions can retain the use of const though, since they make the
variables immutable in the implementation of the function where they're
used.
Now, since we have a const qualified variant of GetPointer(), we can put
it to use in ReadBlock() to retrieve the source pointer that is passed
into memcpy.
Now block reading may be done from a const context.
