Why is this needed:

In grafana/tempo#4525 a new partial response for metric queries is being added. We should show in the UI that results contain partial results.

What would you like to be added:

• Revert temporal fix added in Tempo: Temporarily skip new proto fields #103586 to skip new proto fields and use newly generated types
• Show in the UI when partial results are returned (cc @nadinevehling)
