Camera3: Skip no-op stream configurations.

If configuring the same set of streams more than once, don't actually
call into the HAL for the second and subsequent configure calls, since
they're no-ops.

This can speed up camera operation substantially if the
HAL implementation does not detect no-ops on its own and does a full
shutdown/restart on each configure call.
