Pointer icon refactor for mouse (base)

When PointerChoreographer is enabled, CursorInputMapper no longer
depends on the legacy PointerController. PointerChoreographer is
responsible for accumulating movements, fading/unfading pointers,
and deciding display/coordinates.

Test: atest libinputservice_test
Bug: 293587049
