Add Suspend functions (#3112)

* Add suspend functions

* Disable RGB code if it's disabled

* Add suspend code to ChibiOS for future compatibility

* Add keyboard_init functions

* Change where references so it will compile

* Wrong command chained in wake up kb function

* Fix non-feature file changes

* Add documentation

* Re-add matrix init docs

* add rgblight code to example

* Remove keyboard init stuff for separate PR

# Matrix Initialization Code
Before a keyboard can be used the hardware must be initialized. QMK handles initialization of the keyboard matrix itself, but if you have other hardware like LED's or i²c controllers you will need to set up that hardware before it can be used.

You should use this function if you need custom matrix scanning code. It can also be used for custom status output (such as LED's or a display) or other functionality that you want to trigger regularly even when the user isn't typing.
# Keyboard Idling/Wake Code
If the board supports it, it can be "idled", by stopping a number of functions. A good example of this is RGB lights or backlights. This can save on power consumption, or may be better behavior for your keyboard.
This is controlled by two functions: `suspend_power_down_*` and `suspend_wakeup_init_*`, which are called when the system is board is idled and when it wakes up, respectively.
### Example suspend_power_down_user() and suspend_wakeup_init_user() Implementation
This example, at the keyboard level, sets up B1, B2, and B3 as LED pins.
```
void suspend_power_down_user(void)
{
rgb_matrix_set_suspend_state(true);
}
void suspend_wakeup_init_user(void)
{
rgb_matrix_set_suspend_state(false);
}
```
### `keyboard_init_*` Function Documentation
* Keyboard/Revision: `void suspend_power_down_kb(void)` and `void suspend_wakeup_init_user(void)`
* Keymap: `void suspend_power_down_kb(void)` and `void suspend_wakeup_init_user(void)`
# Layer Change Code
Thir runs code every time that the layers get changed. This can be useful for layer indication, or custom layer handling.
