Define new/delete in libc++ when using libcxxrt

Always turn on LIBCXX_ENABLE_NEW_DELETE_DEFINITIONS, if libcxxrt is used
as the C++ ABI library, since libcxxrt does not provide the full set
ofnew and delete operators. In particular, the aligned versions of these
operators are completely missing. This primarily addresses builds on
FreeBSD, as this platform uses libcxxrt by default.

Also, attempt to provide a FreeBSD.cmake cache file, with hopefully sane
settings, partially copied from the Apple.cmake cache file. This needs
more work, probably some additions to ci build scripts (although I am
not aware of any 'official' FreeBSD build bots).
