  -----------
  [mlir][LLVM] Add support for DIModule metadata

This commit adds a DIModuleAttr to the set of debug info attributes and
extends the LLVM IR import and export to support it.

DIModule metadata is missing in the LLVM LangRef and cannot be produced
from C or C++ input. So far, we only observed classic flang producing
such DI metadata.
