Change the prototype of matrix_output_unselect_delay() (#13045)

The prototype of matrix_output_unselect_delay() has been changed as follows.

```c
void matrix_output_unselect_delay(uint8_t line, bool key_pressed);
```

Currently, no keyboard seems to be redefining `matrix_output_unselect_delay()`, so there is no change in the system behavior.

With this change, the keyboard level code can get some optimization hints, for example, the following.

```c
 void matrix_output_unselect_delay(uint8_t line, bool key_pressed) {
     /* If none of the keys are pressed,
      *  there is no need to wait for time for the next line. */
     if (key_pressed) {
 #ifdef MATRIX_IO_DELAY
 #  if MATRIX_IO_DELAY > 0
         wait_us(MATRIX_IO_DELAY);
 #  endif
 #else
         wait_us(30);
 #endif
     }
}
```
