This class was only ever implemented by ProcessManager, and had two methods WakeEventPage() and IsEventPageSuspended(). IsEventPageSuspended() was only used in a single test file, and just checks that there is no background host for an extension. This can be trivially done by checking GetBackgroundHostForExtension() (which is what the implementation did). WakeEventPage() is called by numerous sites, but all of them do so by accessing the ProcessManager. No sites accept or use the class as the EventPageTracker, so having a separate class that the ProcessManager inherits from is unnecessary.

This will become a reusable extensions module. It implements the core parts of Chrome's extension system, and can be used with any host of the content module.
Some extensions code that is not Chrome-specific still lives in //chrome/browser/extensions and will be moved here.
