Module import implementation class that provides methods to import globals and functions from an LLVM module into an MLIR module.
It holds mappings between the original and translated globals, basic blocks, and values used during the translation. Additionally, it keeps track of the current constant insertion point since LLVM immediate values translate to MLIR operations that are introduced at the beginning of the region.
