  -----------
  [MLIR][LLVM] Reject distinct generic metadata on import (#212455)

Reject distinct nodes when converting generic LLVM metadata into LLVM
dialect attributes because `MDNodeAttr` cannot preserve node identity.
Apply the policy recursively so top-level and nested nodes use the
existing unsupported-metadata failure path while finite acyclic uniqued
nodes remain importable.
