[CMake] Handle in-tree libc++ for sanitizer tests

Browse Source 
We have been relying on the logic for C++ ABI library for sanitizer
tests but that's incorrect since most tests require a full C++ library
and not just C++ ABI. This change tries to address this by using the
dependency on libc++ if available.
