Added power tracking api (#12691)

* Add power tracking API to lufa and chibios targets

* power.c: Pass through power state to the notify function

* power: added notify_power_state_change_user too.

* making it pass the PR linter

* Add a POWER_STATE_NO_INIT state, that we start in before calling power_init();

* Rename *power* to *usb_power*

* removing stray newline

* Rename usb_power* to usb_device_state*

* Update quantum/usb_device_state.h

* Fix comment

* usb_device_state.h: Don't include quantum.h, only the necessary headers.
