Update calamity@'s histogram expiries.

This CL extends the histogram expiry of:
- SiteEngagement.*
- HostedAppFrame.WrenchMenu.MenuAction
- Extensions.LoadCreationFlags
- BookmarkManager.CommandExecutedFromKeyboard
- History.ExpireVisits*

Most of these are useful metrics for understanding how users are using
our products, and sudden changes in these may indicate unexpected side
effects of other changes.
