Bug 1575008 - WebGPU implementation basis r=webidl,baku
This change vendors `wgpu` library in-tree and hooks up the initialization bits. It implements adapter and device initialization and adds a simple test. Current status: - [x] Architecture - [x] figure out the IPC story - [ ] move wgpu crates into a dedicated folder (let's follow up with this) - [x] Review - [x] WebIDL changes by DOM peers - [x] Linux - [x] avoid depending on spirv_cross - gfx-rs/wgpu#371 - [x] macOS - [x] due to cross-compiling shaders - gfx-rs/gfx#3047 - [x] need the dependency update - [x] stop using gcc - SSheldon/rust-objc-exception#5 - [x] unexpected SSL header collision - https://bugzilla.mozilla.org/show_bug.cgi?id=1592398 - [x] undefined Metal symbols - [x] Windows - [x] due to "ipc-channel" not supporting Windows yet - servo/ipc-channel#233 - [x] due to some exceptional stuff - grovesNL/spirv_cross#121 - [x] undefined symbol: `D3D12CreateDevice` - [x] d3d12.dll is not found, dxgi1_4 doesn't present - [x] d3d11.dll and dxgi.dll need to be explicitly loaded on win32 mingw - gfx-rs/gfx#3076 - [x] libbacktrace fails to link on win32 mingw - [x] Android - [x] spirv-cross fails to build - KhronosGroup/SPIRV-Cross#1193 Update-1: We decided to go with IPDL mechanism instead of Rust based ipc-channel (or any alternatives), which unblocks Windows build. Update-2: It appears that WebGPUThreading isn't needed any more as the child thread (and its event loop) is now managed by IPDL infrastructure. This PR removes it 🎉 . Update-3: InstanceProvider is also removed. Update-4: All set, the try is green, waiting for dependent changes to go in.
