[FR] Include clang-scan-deps in the ndk

[yujincheng08]

Description

Since llvm-16 now supports p1689, if clang-scan-deps is included in the ndk, we can use c++ modules with a newer version of cmake (say 3.26+).

I think this should be considered a bug, not a feature request. C++20 modules don't work without clang-scan-deps. Hopefully all you need to do is include executable file in the NDK and we can start using C++20 modules. (If we install our own CMake and Ninja, which is easy.)

This is already in the next compiler, it just hasn't shipped yet.

When is NDK r27 going to be released?
