anv: Add an anv_execbuf helper struct 

This commit adds a little helper struct for storing everything we use to
build an execbuf2 call.  Since the add_bo function really has nothing to do
with a command buffer, it makes sense to break it out a bit.  This also
reduces some of the churn in the next commit.
