Alerting: Filtering improvements

[konrad147]

• Labels' values containing commas are not working #56875
  We support two ways of searching by labels:
  - key=value
  - {key="value"}
  Maybe we should stick to only one (probably the latter as it allows supporting commas). However, typing without brackets and quotes is faster
• Would be good to use controlled components for filter inputs if possible
• Some filters use debounce, others do not
• SilencesFilter could use MatcherFilter to avoid code duplication
• General RWD improvements
