Add a block list to IconManager

Things are always a little wonky with the status bar icons, but
basically there is one (1) StatusBarIconController which funnels status
icon information to all IconManagers, of which there are typically three
(3) - Regular status bar, keyguard status bar, and quick settings

This CL implements a simple blockList at the IconManager level, so that
icons can be excluded for a given manager (and thus a given UI), and
blocks the following icons from keyguard and status bar: alarm, vibrate/mute

More can easily be added by adding them to the blocklist
