Make reVC use a WebGPU implementation of librw instead of OpenGL or DirectX

[AltronMaxX]

About WebGPU / wgpu

wgpu is a cross-platform, safe, pure-Rust graphics API. It runs natively on Vulkan, Metal, D3D12, and OpenGL; and on top of WebGL2 and WebGPU on wasm.

TODO:

• Implement WGPU and check parity with other rendering backends in game.
• [] Remove other librw targets from code.
• [] Clean useless comments.

For now, the source code is available here:

• https://github.com/AltronMaxX/reVC
