Haptic feedback generalized - DRV2605 and solenoids (#4939)

* initial work to add eeprom to haptic feedback and decouple the feedback process from keyboards

* Haptic feedback enhancements: on/off toggle working, feedback order working
todo:
-work on modes switching
-get modes switching to save to eeprom

* haptic enhancement - eeprom and modes added

* Added set and get functions for haptic feedback

* initial implementation of solenoids under haptic feedback

* changed eeprom to 32 bits to reserve blocks for future features

* start documentation of haptic feedback

* change keycode per comment from reviewers

* typo fixes

* added eeprom for solenoid configs

* added solenoid and docs

* Add/fix default parameters configs, improve docs

* more doc cleanup

* add in solenoid buzz toggle, clean up doc

* some fixes for error in compiling solenoid

* fix a chibios specific i2c read function and added one for AVR controllers in DRV2605L.c

* fixes for avr side issues

* update keymap

* fix keymap compile error

* fix bugs found during solenoid testing

* set pin that is not powered during bootloader

* added warning about certain pins on the MCU may trip solenoid during DFU/bootloader
