anv/cmd_buffer: Move state base address re-emit into ExecuteCommands

Browse Source 
This has two primary advantages.  First, it means that the batch_chain code
knows less about the actual command buffer contents which is good because
improves separation.  Second, it means that it only gets re-emitted once
after all of the secondaries instead of once after each secondary which is
just wasteful.  It also has the advantage of cleaning the code up a bit.
