d3d12: Add GetD3D12Device for querying ID3D12Device from WGPUDevice.
Chrome will needs to get a ID3D12Device for decoder/DComp. Currently Chrome's D3D11 decoder fetch the device from ANGLE/Dawn, while for D3D12 it creates the device by itself maybe using different setup(feature levels, etc) from ANGLE/Dawn. Though the device is per-adapter, the behavior of the creation with different setup is unclear.
To make sure decoder and renderer are always consistent on the device settings, we better share the device from ANGLE/Dawn if possible.
