Add kick start to extruder auto fans

[Bob-the-Kuhn]

This PR extends the kick start function/feature to the extruder auto fan(s).

This is done by creating a structure that uses the variable kick_active to keep track of the fan state and the variable kick_end to track the time remaining in the kick period. kick_active's tracking duplicates the fanState variable and adds the kick state.

  fanState = {off, on}
  kick_active = {off, kick, on}

There are two logic changes in temperature.cpp:

• state transitions for the variable kick_active
• additional versions of the _AUTOFAN_SPEED() macro that incorporate the kick power setting

TESTING
A simple two extruder system was tested on a STM32F446 based BTT Octopus V1.1

OPEN ITEMS

• Look at if the variable f or the variable realFan should be used to index the new structure. On my simple two extruder system they're always the same.

Reminder: PR #24092 is still pending If you like messing with fan kickstarts, the only thing holding up that PR is implementing the kickstart. I was aiming to save RAM and to prevent the class from using more memory or flash than the existing fan code, and I haven't revisited it in a while due to other business. It would be good to finish that PR and then we won't have to implement a separate block of kickstart code for every future fan that needs a kickstart feature.

@thinkyhead - I like your idea of a unified approach. I'll close this PR and switch to working on PR #24092 as time permits.
