Introduce PointerChoreographer stage in C++

PointerChoreographer will be the new inputflinger component responsible
for managing the pointer icons drawn on the screen.

In this CL, we set up the PointerChoreographer InputListener stage,
which will be created when the choreographer is enabled.

Bug: 293587049
Bug: 278783893
Test: adb shell setprop persist.input.enable_pointer_choreographer 1;
      boot
