(#99398)Add metadata to Diagnostic. Motivation: we have a use case where we want to do some filtering in our customized Diagnostic Handler based on some customized info that is not `location` or `severity` or `diagnostic arguments` that are member variables of `Diagnostic`. Specifically, we want to add a unique ID to the `Diagnostic` for the handler to filter in a compiler pass that emits errors in async tasks with multithreading and the diagnostic handling is associated to the task. This patch adds a field of `metadata` to `mlir::Diagnostics` as a general solution. `metadata` is of type `SmallVector<DiagnosticArgument, 0>` to save memory size and reuse existing `DiagnosticArgument` for metadata type.
