Support for InputDevice ViewBehavior
This change creates a struct within InputDeviceInfo to hold View related
behaviors of an input device. Currently, a single behavior is supported:
device.viewBehavior_smoothScroll. This can be specified in an IDC file
to hint clients of the InputDevice that they should animate scrolls for
motion events generated by the InputDevice.
Bug: 246946631
Test: add property in IDC, check API returns expected value
Test: atest frameworks/native/services/inputflinger/tests/InputReader_test.cpp
