From: Deepak Rawat <drawat.floss@xxxxxxxxx>
With SM5 capability a new version of streamoutput is supported by device
which need backing mob and a new field. With this change the new command
is supported in command buffer.
v2: Also track streamoutput context binding in binding manager.
v3: Track only one streamoutput as only one can be set to context.
v4: Fix comment typos
