Load TYPE_RESOURCE icons using per-display context (for system icons)

Before this change, if the res package was "android", we were always getting the drawable from Resources.getSystem() (which are associated to the default display).

After this change, we're using resources associated with the context provided to the Icon.

This should be always correct as the package name is get from the context.

Test: show statusbar in multiple displays, change density of the default one, verify icons on the other displays don't change
