charmpp: disable pre-7.0.0 macOS builds with clang@7: (#28221)

Browse Source 
Charm++ versions below 7.0.0 have build issues on macOS, mainly due to the
pre-7.0.0 `VERSION` file conflicting with other version files on the
system: https://github.com/UIUC-PPL/charm/issues/2844. Specifically, it
conflicts with LLVM's `<version>` header that was added in llvm@7.0.0 to
comply with the C++20 standard:
https://en.cppreference.com/w/cpp/header/version. The conflict only occurs
on case-insensitive file systems, as typically used on macOS machines.
