hall_filament_width_sensor: max filament diameter

Add support for maximum filament diameter to hall filament width sensor.
If the diameter of the filament diameter is larger than the limit, the
virtual runout sensor will trigger. The default value is set to maximum
flow adjustment threshold to prevent oversized filament from clogging.
