i915/gem_sync: Make switch-default asymmetric

To make the demonstration of the cheeky preemption more impactful, make
the second context a nop to contrast the first being 1024
MI_STORE_DWORD_IMM. Then if we execute and wait on the second context
before executing the first, the client latency is even more drastically
reduced.

To more clearly show any effect on wait reordering, measure the
alternative path and present both.
