According to https://w3c.github.io/timing-entrytypes-registry/#registry, unlike other performance entries, `event` and `first-input` entries have their own algorithms to determine whether it can be added to observers. This patch factors some code to allow such algorithms can be implemented. Differential Revision: https://phabricator.services.mozilla.com/D102034
