Port patch

In the attached diff, I have disabled the cmake flag 'runtime_cxxmodules' and 
accommodated the rest of the port files accordingly.

A recent change in LLVM/Clang modulemap handling has caused ROOT (which builds
its own patched version of LLVM/Clang for JIT C/C++ compilation, e.g. from the
ROOT terminal) in the upstream source code to hack modulemap definitions on a
case-by-case OS release-dependent basis on macOS, which also compiles ROOT with
a LLVM/Clang compiler.
Once a more robust solution has been found in the upstream code, we can revert
to enabling 'runtime_cxxmodules' in the port.
For now, my attempts at continually patching ROOT for FreeBSD 13.3+, 14.0+ and
15.0 have proven too error-prone, and a package built on 14.0, for example, and
distributed to both 14.0 and 14.1 would otherwise only work on 14.0 in the best
of cases.

I have tested building of the port on 14.1-amd64 with the default options 
enabled and with each individual port option enabled/disabled.
