New VerifiedInputEvent api

The Verified{Input/Key/Motion}Event api are the same as
{Input/Key/Motion}Event api.
The VerifiedMotion class is the same as the MotionEvent class, but
contains less information. It only contains the information that the
system is able to verify.
Same applies to VerifiedKeyEvent.

The class VerifiedInputEvent contains common information applicable to
both Key and Motion.

Test: atest VerifiedKeyEventTest VerifiedMotionEventTest
