Revert 143896 - Filtered events.

(Reverting as it breaks platform app's onLaunched event dispatch).

Makes web_navigation events support filters, eg:

chrome.webNavigation.onBeforeCommitted.addListener(callback, {url: [{hostSuffix: 'google.com'}]});

Now callback will only be called when the event has a URL with a host suffix of google.com.
