ref(browser): Refactor browser integrations to use processEvent (#9022)
This refactors browser integrations to use the new `processEvent` hook on the Integrations interface. It also updates Replay to register it's event processor on the client, not globally. This is also needed to ensure the order is somewhat stable, as global processors are run separately from the client ones.
