Switch SurfaceFlinger to HWC 2.0

Enables SurfaceFlinger to speak to version 2.0 of the Hardware Composer
HAL instead of version 1.x (also removing support for the framebuffer
HAL). By default, however, this functionality is disabled. In order to
enable it, USE_HWC2 must be set to true in Android.mk.
