  Log Message:
  -----------
  Recommit [C++20] [Modules] [ClangScanDeps] Enable to print make-style dependency file within P1689 format (4/4)

Required in https://reviews.llvm.org/D137534.

The build systems needs the information to know that "header X changed,
scanning may have changed, so please rerun scanning". Although it is
possible to get the information by running clang-scan-deps for the
second time with make format, it is not user friendly clearly.
