Reduce Kill Pin Wait

[InsanityAutomation]

While working with @p3p on an issue in the simulator where we were triggering the kill pin, we noticed a very pronounced delay. In the case of the simulator linux HAL, the idle loop rate was 500hz and therefore this added significant dwell to the execution of the stop function. Looking at the code, we see the delay is called in cycles, not ms. This function cannot use the safe_delay calls as it is inside the manage inactivity function. The consensus in discussion on discord is that as a safety function, we should only be debouncing for signal noise, not accidental press. Most common actuation of a safety button is a rapid slap, not a press and hold.

Therefore we have 2 options. 1. Reduce the time to whats reasonable as a debounce or 2. Count ticks. For the moment, I opted for the simpler reduction and allowed an override for especially noisy systems. I updated the comment in order to point out explicitly that this should function as a debounce.
