gn build: libcxx: Sync file list and always define _LIBCPP_ABI_VERSION.

Browse Source 
The CMake side always defines _LIBCPP_ABI_VERSION. If we do not, we will
at least get -Wundef warnings in the test suite (upgraded to errors)
and it looks like we will end up building the library incorrectly as well.

With that, most of the libc++ test suite passes (with a manually written
lit.site.cfg) aside from some parts related to C++ modules which we
don't support yet.
