Allow for removal of hysteresis on 4x encoders (#13698)
* Remove hysteresis on 4x encoders Sometimes, controller skips encoder pulses and when it returns to default position, the encoder_pulses variable isn't equals 0. And when I turn encoder in opposite direciton, it skips first click becase of encoder_pulses crosses zero. To prevent this, I add the ENCODER_DEFAULT_POS constant, and reset encoder_pulses into 0 when the state variable equals ENCODER_DEFAULT_POS. * Documentation for ENCODER_DEFAULT_POS

#define ENCODER_RESOLUTIONS { 4, 2 }

+For 4× encoders you also can assign default position if encoder skips pulses when it changes direction. For example, if your encoder send high level on both pins by default, define this:
+
+```c
+#define ENCODER_DEFAULT_POS 0x3

## Split Keyboards
If you are using different pinouts for the encoders on each half of a split keyboard, you can define the pinout (and optionally, resolutions) for the right half like this:
