Adding --task_worker_spin_us= flag to spin for a bit.
The flag allows iree-* tools to override the spin value for benchmarking.
The new iree_task_executor_options_t struct consolidates the existing
options and exposes the setting for use by hosting applications.
We default to not spinning because in general it's not a good thing to do.
