Roll src/buildtools/third_party/libc++/trunk/ d9040c75c..69897abe2 (1149 commits)

It has been a long time since the last libc++ roll, so many extra
changes were required:
- New libc++ cpp files added to gn
- Re-generated prebuilt gvr_shim for Android
- Updated absl symbols for libc++ roll (crbug.com/1166430)
- Updated static initializer expectations for second libc++ iostream
  initializer
- Disabled checked_iterator test relying on std::copy implementation
  details (crbug.com/1166360)
- Added global availability macro for crbug.com/1166707
- Adjusted some pragma max_token limits for new headers
- Overrode _LIBCPP_HIDE_FROM_ABI to work around crbug.com/1090975 on Windows
- Defined _LIBCPP_NO_NATIVE_SEMAPHORES to work around crbug.com/1166970
