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

[AltronMaxX]

A strange idea recently came to mind: what if we rewrote librw to use WebGPU? Well, I've made a basic implementation. It works, though not quite as fully as "vanilla" reVC yet.

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.

Thanks to this, we now have a Vulkan renderer on Linux by default. In the future, I plan to add an option in the settings to change the preferred backend in-game.

For now, the source code is available here:
