Summary:
An ubuntu-latest image update caused build failures, where GTest importing chrono headers caused an error inside of stdlib++ when being compiled by Clang.
This switches to explicitly asking for libc++ (LLVM stdlib) in the reference Ubuntu Clang build instead of stdlibc++ (GCC stdlib).
We don’t force this in CMake logic, to not force a specific stdlib for users compiling Yoga alongside other libraries. E.g. https://github.com/facebookexperimental/libunifex/issues/86
