ameerj 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.

ReinUsesLisp a63a0daa5e gl_arb_decompiler: Implement an assembly shader decompiler
Emit code compatible with NV_gpu_program5.
This should emit code compatible with Fermi, but it wasn't tested on
that architecture. Pascal has some issues not present on Turing GPUs.

lat9nq a290aac5b3 Make compatible with the current MinGW cross-compiler
The Docker image was just updated to use Arch Linux instead of Ubuntu. This PR
sets the compiler names to reflect how they are installed on the Arch Linux
Docker image. Fixes "x86_64-w64-mingw32-g++-posix is not a full path and was not found in the PATH." errors in CMake.

drop the later and only "specialize" the shader while decoding it.

ReinUsesLisp 4e35177e23 shader_ir: Implement VOTE
Implement VOTE using Nvidia's intrinsics. Documentation about these can
be found here
https://developer.nvidia.com/reading-between-threads-shader-intrinsics

Instead of using portable ARB instructions I opted to use Nvidia
intrinsics because these are the closest we have to how Tegra X1
hardware renders.

To stub VOTE on non-Nvidia drivers (including nouveau) this commit
simulates a GPU with a warp size of one, returning what is meaningful
for the instruction being emulated:

* anyThreadNV(value) -> value
* allThreadsNV(value) -> value
* allThreadsEqualNV(value) -> true

ballotARB, also known as "uint64_t(activeThreadsNV())", emits

VOTE.ANY Rd, PT, PT;

on nouveau's compiler. This doesn't match exactly to Nvidia's code

VOTE.ALL Rd, PT, PT;

Which is emulated with activeThreadsNV() by this commit. In theory this
shouldn't really matter since .ANY, .ALL and .EQ affect the predicates
(set to PT on those cases) and not the registers.

James Rowe 08fcf41b0a QT Frontend: Add a Loading screen with progressbar
With shader caches on the horizon, one requirement is to provide visible
feedback for the progress. The shader cache reportedly takes several
minutes to load for large caches that were invalidated, and as such we
should provide a loading screen with progress.

Adds a loading screen widget that will be shown until the first frame of
the game is swapped. This was chosen in case shader caches are not being
used, several games still take more than a few seconds to launch and
could benefit from a loading screen.

James Rowe 9e847b7549 Build: Enable SSL in mingw by linking against WinSSL
The mingw builds aren't submitting telemetry because the curl library
they are linked against is configured to use openSSL and openSSL looks
for the certificates in the users home folder. This keeps it from
contacting web services because it can't communicate over SSL.

This commit adds a download in mingw builds that will download a
precompiled curl for mingw linked against winssl and sspi.
