Add Dip Switch as a core feature (#6140)

Browse source 
* Add Dip Switches as a core feature

* Add documentation for Dip Switch feature

* Update Preonic Rev3 to use new feature and remove custom matrix

* Apply suggestions from code review

Co-Authored-By: noroadsleft <18669334+noroadsleft@users.noreply.github.com>

* Remove custom matrix line completely

Rather than just disabling it

Co-Authored-By: fauxpark <fauxpark@gmail.com>

* DIP changes

Co-Authored-By: fauxpark <fauxpark@gmail.com>

* Use better check for DIP Switch configuration

* Add to show features

* Add bitmask callback for dip switch

* Fix OLKB Boards dip switch config

* Update docs to include bitmask example

* Fix comments/documentation

Co-Authored-By: fauxpark <fauxpark@gmail.com>

* Fix issues with docs and use example from @tuzonghua

* Fix wording

Co-Authored-By: fauxpark <fauxpark@gmail.com>

* Fix example to use proper formatting

Bad, BAAAAAAD drashna!!!

* Handle dip switch initialization better

# DIP Switches
DIP switches are supported by adding this to your `rules.mk`:
DIP_SWITCH_ENABLE = yes
and this to your `config.h`:
```c
#define DIP_SWITCH_PINS { B14, A15, A10, B9 }
```
## Callbacks
The callback functions can be inserted into your `<keyboard>.c`:
```c
void dip_switch_update_kb(uint8_t index, bool active) {
dip_switch_update_user(index, active);
}
```
or `keymap.c`:
```c
void dip_switch_update_user(uint8_t index, bool active) {
switch (index) {
case 0:
if(active) { audio_on(); } else { audio_off(); }
break;
case 1:
if(active) { clicky_on(); } else { clicky_off(); }
break;
case 2:
if(active) { music_on(); } else { music_off(); }
break;
case 3:
if (active) {
#ifdef AUDIO_ENABLE
PLAY_SONG(plover_song);
#endif
layer_on(_PLOVER);
} else {
#ifdef AUDIO_ENABLE
PLAY_SONG(plover_gb_song);
#endif
layer_off(_PLOVER);
}
break;
}
}
```
Additionally, we support bit mask functions which allow for more complex handling.
```c
void dip_switch_update_mask_kb(uint32_t state) {
dip_switch_update_mask_user(state);
}
```
or `keymap.c`:
```c
void dip_switch_update_mask_user(uint32_t state) {
if (state & (1UL<<0) && state & (1UL<<1)) {
layer_on(_ADJUST); // C on esc
} else {
layer_off(_ADJUST);
}
if (state & (1UL<<0)) {
layer_on(_TEST_A); // A on ESC
} else {
layer_off(_TEST_A);
}
if (state & (1UL<<1)) {
layer_on(_TEST_B); // B on esc
} else {
layer_off(_TEST_B);
}
}
```
## Hardware
One side of the DIP switch should be wired directly to the pin on the MCU, and the other side to ground. It should not matter which side is connected to which, as it should be functionally the same.

* [Combos](feature_combo.md) - Custom actions for multiple key holds.
* [Command](feature_command.md) - Runtime version of bootmagic (Formerly known as "Magic").
* [Debounce API](feature_debounce_type.md) - Customization of debouncing algorithms, and the ability to add more/custom debouncing.
* [DIP Switch](feature_dip_switch.md) - Toggle switches for customizing board function.
* [Dynamic Macros](feature_dynamic_macros.md) - Record and playback macros from the keyboard itself.
* [Encoders](feature_encoders.md) - Rotary encoders!
* [Grave Escape](feature_grave_esc.md) - Lets you use a single key for Esc and Grave.
