  [mlir] Add support for multi-parts diagnostics (#217804)

Under the current MLIR diagnostic infrastructure, emitting multiple
remarks at the same location requires calling the remark API multiple
times; moreover, every call to remark prints a note. This PR introduces
the concepts of "parts" To diagnostics. A streaming manipulator, called
`next`, similar to `std::endl` can be used to split multiple parts into
a single `InFlightDiagnostic`. This can be used for example to emit
multiple remarks at the same location, share the notes for those
remarks.
