EventLogging: break up MobileWebClickTracking

The MobileWebClickTracking table is getting huge. Splitting it into
several schemas will make it easier to manage.

The new schemas are:
* MobileWebWatchlistClickTracking
* MobileWebDiffClickTracking
* MobileWebMainMenuClickTracking
* MobileWebUIClickTracking
