Manually roll build on 10.6 to include windows infra fix

Roll /build:
https://chromium.googlesource.com/chromium/src/build/+log/339f8c6..6180903f

This includes https://crrev.com/c/3874828 which fixes flaky
compilation problems seen on the 10.6 V8 trybots:
https://ci.chromium.org/ui/p/v8/builders/try/v8_win_compile_dbg/b8800699999726054577/overview

This also rolls buildtools, libcxx and clang, since they have
dependencies with changes on /build.

This deps updates do not affect the Chrome release as it only updates
deps used to build V8 stand-alone, not V8 in Chrome.

This also also disables the extra-semi check which was enabled in the
same roll as otherwise a lot of source fixes need to be merged, too.
