This CL cleans up and activates |decode_using_client_picture_buffers_|
after recent power consumption measurements done by the Intel folks
reveal that there should be no regression, and also because skipping
the Vpp has a huge impact in memory consumption since Va doesn't need
to allocate ~13/14 Buffer Objects inside (see crbug.com/909926).
