Add gestures library to whole_static_libs for input reader

The next CL in this series causes linker errors for libinputreader_arc
on aosp_bramble-userdebug that were previously hidden by compiler
optimization. It seems that we need to explicitly include
libchrome-gestures as a "whole" static library for
libinputreader_static.

Bug: 251196347
Test: lunch aosp_bramble-userdebug && m libinputreader_arc
