M303 D will now toggle activation of PID_DEBUG output.   This allows the debug capability to be built into the firmware, but turned on and off as needed.

Apply minimum `C` in `M303`. `PID_autotune()` needs to be called with a 'C'ycles-parameter >2 to give meaningful (different from 0) PID-factors. Therefore silently raise C to 3. Fixing one aspect of #13104

* Optimize target_extruder, ignore T with mixing
* Give G-code Tn parity with tool_change

Implement AVR Platform

Following up on #3231

Keep "astyled" reformatting

Apply `ENABLED` / `DISABLED` macros to files needing only a small
number of changes.
