Enable PWM Support for Planck EZ Indicator Lights (#6473)

* remove led layer code

* enable PWM on STM32F303

* Unusable PWM code

* Updated PWM Stuff?

* PWM Semi-working

* Both LEDs working at the same time

* Update names

* Add led level functions

* Add LED levels and persistent settings

* Revert change due to issues with timing related code

* Review feedback and minor cleanup
