Use renderengine on mediaserver side

To make sure the thumbnail generation doesn't block
surfaceflinger's rendering, use a separate render context
inside mediaserver at default priority.

Replace surfaceflinger side BufferQueueLayer (SurfaceControl)
with our own lightweight version, and mirror the setup of
renderengine to capture the buffer.
