hall_filament_width_sensor: Add filament switch values to status

`hall_filament_width_sensor` contains a runout sensor object internally.
This exposes those values in the API status result.

```
SEND: {"id":123,"method":"objects/query","params":{"objects":{"hall_filament_width_sensor":["enabled","filament_detected","is_active","Diameter","Raw"]}}}
GOT: b'{"id":123,"result":{"eventtime":199567.823596603,"status":{"hall_filament_width_sensor":{"enabled":true,"filament_detected":true,"is_active":true,"Diameter":1.9499999999999986,"Raw":6113}}}}'
```

The duplication of `is_active` and `enabled` seems confusing, but both
of these can be independently manipulated by GCode:

```
SEND: {"id":123,"method":"gcode/script","params":{"script":"DISABLE_FILAMENT_WIDTH_SENSOR"}}
GOT: b'{"id":123,"result":{}}'
SEND: {"id":123,"method":"objects/query","params":{"objects":{"hall_filament_width_sensor":["enabled","is_active"]}}}
GOT: b'{"id":123,"result":{"eventtime":199770.446013297,"status":{"hall_filament_width_sensor":{"enabled":true,"is_active":false}}}}'

SEND: {"id":123,"method":"gcode/script","params":{"script":"SET_FILAMENT_SENSOR SENSOR=hall_filament_width_sensor ENABLE=0"}}
GOT: b'{"id":123,"result":{}}'
SEND: {"id":123,"method":"objects/query","params":{"objects":{"hall_filament_width_sensor":["enabled","is_active"]}}}
GOT: b'{"id":123,"result":{"eventtime":199847.927726196,"status":{"hall_filament_width_sensor":{"enabled":false,"is_active":false}}}}'
```
