WebGPU: Implement glBufferData and glBufferSubData Define several usages for WebGPU buffers that map to wgpu buffer usage flags. Maintain a set of buffers by usage and a serial of the one with the most recent data. Defer creation of the buffer as long as possible to take advantage of the WebGPU mapAtCreation flag for data upload. If we ever have to unmap these buffers, staging buffers must be used to upload afterwards. Add some helpers for getting Device and Instance from a gl::Context.
