In current code swapRect optimization is enabled for the use cases,
where only one layer is updating. this change will enable swapRect for
use cases where more than one layer is updating.

In cases where we need to clear multiple regions we are
sending union of those regions in single call. Instead calling
clear for independent clear regions will help in achieving
performance gain by reducing time taken for solidFill.

No need to clear a non updating region in case of swapRect.
Use dirtyRect value of updating layer to achieve this.
Before using dirtyRect value map it to respective displayFrame,
as dirtyRect is with respect to sourceCrop.

Check for planeAlpha value as well along with HWC_BLENDING_NONE
as the latter is set if layer is Opaque independent of planeAlpha.

Right now clear is already being done in SF using GPU for
HWC_BLIT layers, no need to clear layers a second time.

For copybit cases we should clear wormhole region
rather than nonwormhole. Adding support to calculate
and clear the same.
