[llvm] [MLGO] Only configure tests with `LLVM_INCLUDE_TESTS` (PR #121293)

[Jonas Hahnfeld via llvm-commits]

https://github.com/hahnjo created https://github.com/llvm/llvm-project/pull/121293

This allows downstream customers to remove all test directories and save quite some space when only building with `LLVM_INCLUDE_TESTS=OFF`.
