Alerting: Add filtering for Silences (#39109)

* Add filtering for Silences page

* Add tests Silences and SilenceEditor

* pr feedback: add field validation and test refactor

* Add test for checking content

* fix overflow for validation error message

* increase login threshold for pa11y

* Make silence filter state its own type and function
