  Log Message:
  -----------
  [C++20] [Modules] Emit a warning if the we load the modules by implicit generated path

A step to address https://github.com/llvm/llvm-project/issues/62707.

It is not user friendly enough to drop the implicitly generated path
directly. Let's emit the warning first and drop it in the next version.
