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.
