hwc: Disable HW vsync for some targets

7x27A, 8x25 and 8x55 do not support HW vsync yet.
This change checks for their MDP version and disables HW vsync
on them. This change should be reverted once hardware vsync is
available on these targets.

overlay: Refactor State Transitions.

Refactor transitions by templatizing to have default behavior for most cases
and full specializations for specific cases.
Partial specialization of functions is not allowed, so create templatized
intermediate functions for those use cases.
For ex: if we have 8 states, we don't need 8x8 transition handlers.

Add and define OV_DUAL_DISPLAY state.
Add a GenericPipe for subtitles to OV_2D_VIDEO_ON_PANEL_TV state.
Add a 2D_VIDEO_ON_TV state and its transitions.

 libhwcomposer: Reset composition types on idle timeout.

 SurfaceFlinger re-creates HWC worklist only for new frame and on
 layer geometry change. Invalidate triggered by idle timeout
 refreshes the existing worklist retaining its previous
 composition type. So its MDP comp's responsibility to clear
 layer composition types to HWC_FRAMEBUFFER on timeout.
