Introduce accessibility large pointer icons.
This patch does the following things:
- add new graphic assets of large icons for accessibility needs
(imported from ChromeOS data)
- add the logic to choose the set of normal icons or accessibility icons
- make InputManagerService to observe the settings change, so that
it can reload the new resources
This patch misses non-1x graphic though, because ChromeOS doesn't
have such data.
