  -----------
  [flang] Support discovering LLVM/Clang/MLIR without explicit *_DIR (#122639)

Support discovering LLVM, Clang and MLIR via the standard CMake logic in
addition to explicitly specified `LLVM_DIR`, etc. To prevent breaking
anyone's workflow the way #120914 did, this change explicitly introduces
two possible code paths based on variables provided:

1. If `LLVM_DIR`, etc. are defined, the current logic is used as-is.

2. If they are not defined, `find_package()` is called normally to
discover the packages using the standard CMake logic, and the discovered
paths are added
