fix(meson): Support libc++ >=9.0.0

From LLVM libc++ documentation:
"Prior to LLVM 9.0, libc++ provides the implementation of the
filesystem library in a separate static library."

Now the filesystem library (not the experimental one) is shipped
inside the libc++.so library.

Check if '-lc++fs' link flag is needed and supported before adding
it.
