Roll/update build-related dependencies This may help with ASAN issues seen on Windows ASAN (see bug 347169607). Details: - Roll depot_tools, build, buildtools, third_party/libc++/src, third_party/libc++abi, tools/clang, tools/rust - Newly-required abseil-cpp issue workaround is copied from Chromium - Add llvm-libc because libc++ now depends on it. llvm-libc/BUILD.gn is copied from Chromium. - Moved dsymutil into 'hooks' section instead of 'deps' section to match Chromium (but with 'dawn_standalone and' prepended). - Require use_custom_libcxx=false when building with MSVC, because libc++ doesn't build on MSVC right now. This setting was changed for the MSVC bots in bsheedy's CL: https://crrev.com/c/6192201 - Work around a spurious MSVC warning that only appears on (CMake?) release bots. I don't know what it has to do with any of the dependencies rolled in this CL. I could not reproduce locally. I think what's happening is MSVC inlines and optimizes `FormatWidth`, and then if none of the cases is hit then `src_width` will be uninitialized. This is arguably correct, but some buggy version of MSVC attributes this issue to the wrong place in the code: `if (dst_width < src_width)`. If my suspicion is correct, it goes away either if inlining is prevented or all codepaths (that return at all) return a value. Rolled all dependencies to match a recent Chromium revision; steps: - Add "custom_vars": { "checkout_rust": True } to .gclient - gclient sync - roll-dep build buildtools tools/clang tools/rust - Manually update the other deps to match Chromium DEPS.

Dawn is an open-source and cross-platform implementation of the WebGPU standard. More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL. Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.
Dawn provides several WebGPU building blocks:
