Auto merge of #66213 - tmiasko:mandatory-error-warn, r=petrochenkov

Make error and warning annotations mandatory in UI tests

This change makes error and warning annotations mandatory in UI tests.
The only exception are tests that use error patterns to match compiler
output and don't have any annotations.

Fixes #55596.
