SF: use shared_ptr to track hwcLayer
Use std::shared_ptr to track hwcLayer pointers.
This is necessary because the calculation of
data for HWComposer is done in Layer and the processing of that
data is done in SurfaceFlinger, and we need to make sure that
the hwcLayer is not destroyed by Layer while or before being
used by SurfaceFlinger.
