Set up a GestureInterpreter and feed it events

This is a minimal setup of the gestures library, in that it doesn't have
a timer provider or property provider, but it's enough to be able to
feed it events and have it report the gestures it has detected.

This CL depends on https://r.android.com/2310648 to pull in the
Android.bp file and `SetCallback` rename from upstream, and
https://r.android.com/2314880 to pull in the deprecation of screen DPI
hardware properties.

Bug: 251196347
Test: connect Apple Magic Trackpad 2, make gestures, check logcat
