  Log Message:
  -----------
  [flang] Handle indirect USE of ancestor module into submodule (#124969)

A USE statement within a submodule (possibly in a nested scope) is not
allowed to USE the submodule's ancestor module directly, but it is
permissible to USE that ancestor module indirectly via another unrelated
module. Don't emit "already present in scope" errors for this case.

Fixes https://github.com/llvm/llvm-project/issues/124731.
