Support loading keyboard layout overlays from resources.

Added the concept of a keyboard layout overlay, which is
a key character map file that has "type OVERLAY".

Added support for loading keyboard layout overlays from
resources dynamically.  The layouts are reloaded whenever they
are changed in the Settings application or an application
is installed.  This is somewhat more aggressive than necessary
so we might want to optimize it later.

Before system-ready, the input system uses just the generic
keyboard layouts that are included on the device system image.
After system-ready, it considers the user's selected keyboard
layout overlay and attempts to load it as necessary.  We need to
wait until system-ready before doing this because we need to
be in a state where it is safe to start applications or access
their resources.
