  [MLIR][LLVM] Preserve unknown function metadata on import

Import representable non-debug function metadata without a kind-specific
dialect conversion into `LLVMFuncOp` `function_metadata`. Preserve repeated
metadata kinds through the generic carrier so LLVM IR import and export can
round-trip the supported generic metadata subset.

Warn and drop attachments outside that subset while continuing to import the
function.
