Use RenderPass CreateAndAppendSQS whenever possible
This CL is a follow up on
265823015. Now RenderPass has function to
create and append SharedQuadState without passing around the owndership,
use this function whenever possible, instead of create SQS and pass it
into RenderPass.
This CL also helps future CL that will expose the default constructor
of SQS, and remove scoped_ptr constructor.
