@Dinistro I'm refactoring the linkage code in preparation for future MLIR-link work. This change doesn't introduce any functional differences but aligns the implementation more closely with LLVM's representation. Previously, the code generated a lookup table to map MLIR enums to LLVM enums due to the lack of one-to-one correspondence. With this refactoring, the generated code now casts directly from one enum to another. (see example: https://godbolt.org/z/WMovbq95q)
