Port DIRECT_PINS from split_common/matrix.c to matrix.c (#5091)

Browse source 
* Port DIRECT_PINS from split_common/matrix.c to matrix.c

* Reorder matrix.c to remove foward declaration and match split_common/matrix.c

* Refactor nano to use DIRECT_PINS

* Reorder matrix.c to remove foward declaration and match split_common/matrix.c

* Add DIRECT_PINS documentation

* Reorder matrix.c to remove foward declaration and match split_common/matrix.c - fix logic from inherited from split_common

* Add DIRECT_PINS documentation - review comments

#### Direct Pin Matrix
To configure a keyboard where each switch is connected to a separate pin and ground instead of sharing row and column pins, use `DIRECT_PINS`. The mapping defines the pins of each switch in rows and columns, from left to right. Must conform to the sizes within `MATRIX_ROWS` and `MATRIX_COLS`, use `NO_PIN` to fill in blank spaces. Overrides the behaviour of `DIODE_DIRECTION`, `MATRIX_ROW_PINS` and `MATRIX_COL_PINS`.
```c
// #define MATRIX_ROW_PINS { D0, D5 }
// #define MATRIX_COL_PINS { F1, F0, B0 }
#define DIRECT_PINS { \
{ F1, E6, B0, B2, B3 }, \
{ F5, F0, B1, B7, D2 }, \
{ F6, F7, C7, D5, D3 }, \
{ B5, C6, B6, NO_PIN, NO_PIN } \
}
#define UNUSED_PINS
/* COL2ROW, ROW2COL */
//#define DIODE_DIRECTION
```
### Backlight Configuration
By default QMK supports backlighting on pins `B5`, `B6`, and `B7`. If you are using one of those you can simply enable it here. For more details see the [Backlight Documentation](feature_backlight.md).

For the `DIODE_DIRECTION`, most hand-wiring guides will instruct you to wire the diodes in the `COL2ROW` position, but it's possible that they are in the other - people coming from EasyAVR often use `ROW2COL`. Nothing will function if this is incorrect.
To configure a keyboard where each switch is connected to a separate pin and ground instead of sharing row and column pins, use `DIRECT_PINS`. The mapping defines the pins of each switch in rows and columns, from left to right. Must conform to the sizes within `MATRIX_ROWS` and `MATRIX_COLS`, use `NO_PIN` to fill in blank spaces. Overrides the behaviour of `DIODE_DIRECTION`, `MATRIX_ROW_PINS` and `MATRIX_COL_PINS`.
`BACKLIGHT_PIN` is the pin that your PWM-controlled backlight (if one exists) is hooked-up to. Currently only B5, B6, and B7 are supported.
`BACKLIGHT_BREATHING` is a fancier backlight feature that adds breathing/pulsing/fading effects to the backlight. It uses the same timer as the normal backlight. These breathing effects must be called by code in your keymap.
