[Keyboard] Sol keyboard conversion to split common (#5773)

* Split common conversion

* Updated serial and encoder pins

* Fixing default folder until r2

* Fixing oled driver on slave split common

* Fixing keymap compile errors

* Fixing oled inactivity timer on slave split common

* Hoisted oled driver task, init, & activity to keyboard.c

* Update keyboards/sol/config.h

Co-Authored-By: XScorpion2 <rcalt2vt@gmail.com>

* Remove TAPPING_FORCE_HOLD
