SF: Add DisplayDevice::initiateModeChange

This CL creates DisplayDevice::initiateModeChange which calls
HWC::setActiveConfigWithConstraints. SF should call DisplayDevice
instead of directly calling HWComposer.
This is a step towards removing the cached display modes from
the HWComposer class.

Test: presubmit
