[clang] [clang] [cmake] Add cmake module dir before using GetDarwinLinkerVersion (PR #86386)

[Michał Górny via cfe-commits]

https://github.com/mgorny created https://github.com/llvm/llvm-project/pull/86386

Move the code adding top-level cmake/Modules directory to CMAKE_MODULE_PATH prior to including `GetDarwinLinkerVersion`, in order to fix standalone builds.

Fixes a regression introduced by 3bc71c2abfa00413fd15cf0e5c08af6ec0d4768b.
