[MLIR][LLVM] Add accessor for LLVMModule and invoke convertDialectAttributes on GlobalOps

This patch seeks to do two things add an accessor method to
retrieve the ModuleTranslations contained LLVM Module for direct
usage by dialects that are being lowered to LLVM-IR. One particular
use case for this is in the OpenMP Dialect, when interfacing
with the OMPIRBuilder in certain cases it is useful to be able
to access the LLVM Module directly.

The second is invoking convertDialectAttributes on GlobalOp's
so as to be able to lower dialect specific attributes that are
applied or lowered onto GlobalOp's.
