hwc: vpuclient: vpuClient implementation

Browse Source 
Vpuclient is the client side for VFM in hwc. It follows the
similar pattern of prepare and draw. It has 2 step prepare
including: setVpuSession and prepare. The setVpuSession function
passes all the layers from the SF list to VFM, which marks
the layers that it can support. After this, the layer
allocation/configuration is done, and finally in prepare the
allocated pipes are passed down to VFM. The draw function
passes the handle to the VFM to draw the video layer.
