Remove all of the pieces except the PointerController and SpriteController over
to frameworks/native in preparation for inputflinger. Those two need to stay in
frameworks/base for now because they depend on Skia currently. In the long run
they should be merged into either the InputManager or the WindowManager rather
than as a part of the inputservice / inputflinger.

Refactored the directory structure so that services can be optionally
excluded. This is step 1. Will be followed by another change that makes
it possible to remove services from the build.
