Subject: [Keymap] Drashna's Hardware Features Experimentations (#6920)

* Change RGBLight pin for Planck Light

Move it to A0, so that the SPI? pins are available for BT hackery

* Add QMK DFU bootloader info

* Add Solenoid

* Disable annoying white LED on bottom

* Enable Solenoid on Corne

* Remove bounds for animations

* Increase debounce for Ergodox EZ to reduce repeat key issues

* Set swap hands key to be a hold-tap key

This way, it's not ANNOYING and doesn't swap the hands inteniontally

* Move MT Alt in Corne keymap

* Re-Add fine tuned control of secrets

* Squash mods to single row

* Add LRA settings to haptic feedback settings for Rev6

* Fix issue with non-Planck EZ keymaps

* Add 40 Percent Nano with Analog Joystick

* Add Collide39 keymap

* Fix OLED printing to be more flavorful

* Fix up Iris GamePad and come cleanup

* Expand OLED char map further

* Add modded characters to keylogger

* Here be dragons

Co-Authored-By: noroadsleft <18669334+noroadsleft@users.noreply.github.com>

* Fix up rules for community layouts

* Some more OLED tweaks

* Add mod mask check function

* Change QMK DFU Audio pin to be correct

* Use manual STM config instead of CTPC for Collide 39
