Remove unused NTP UMA stats.

Remove unused NTP UMA stats.

This deletes four user actions that were added long ago and are no
longer used:
 - MobileFirstEditInOmnibox
 - MobileFocusedFakeboxOnNtp
 - MobileFocusedOmniboxOnNtp
 - MobileFocusedOmniboxNotOnNtp

This also starts recording the FocusLocation user action when the omnibox is
focused; this essentially combines MobileFocusedFakeboxOnNtp,
MobileFocusedOmniboxOnNtp, and MobileFocusedOmniboxNotOnNtp into a single
action.
