Move per-profile prefs into a per-profile object

The location/microphone/tab-access prefs are per-profile and would more
appropriately live on an object scoped to a single profile, rather than
the global GlicLauncherConfiguration.

This CL moves these prefs to a new GlicProfileConfiguration which is
owned by the GlicKeyedService, a per-profile object.

This is a non-functional change.
