This commit adds an undocumented and temporary knob for spawning the reinsertion part of the singleton timer wheel in the interest of reducing delays between wheel ticks. From poking around at this, the default behavior is that the singleton ticking wakes up on an arbitrary thread in the qmaint pool. That's normally desirable, but under heavy load that pool is fairly saturated and that can lead to increased latency in dispatching the ticks. With this commit, when `kumo.set_timeq_spawn_reinsertion(true)` is called during `pre_init`, we'll spawn a dedicated thread to tick the singleton wheel, and each time it dispatches, it will launch the spawned message batch into the qmaint pool. This keeps the pop interval consistent.
