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.

## Changes ## Changes
20231216: The `[hall_filament_width_sensor]` is changed to trigger filament runout
when the thickness of the filament exceeds `max_diameter`. The maximum diameter
defaults to `default_nominal_filament_diameter + max_difference`. See
[[hall_filament_width_sensor] configuration
reference](./Config_Reference.md#hall_filament_width_sensor) for more details.
20231207: Several undocumented config parameters in the `[printer]` 20231207: Several undocumented config parameters in the `[printer]`
config section have been removed (the buffer_time_low, config section have been removed (the buffer_time_low,
buffer_time_high, buffer_time_start, and move_flush_time parameters). buffer_time_high, buffer_time_start, and move_flush_time parameters).
