Ford: log interesting module configuration data ( #31569 )

* Ford: log interesting module configuration data
Ford ECUs have what is called "As-Built Data" which is configured at the
factory/workshop to set what packages/features are enabled on the car.
But they also contain vehicle specific information (VIN, make, model,
weight, wheel base...), DTC information and driver preferences.
I dumped the CAN traffic for the FORScan diagnostic tool to see how it
requests this information from the ECUs.

Using UDS service `READ_DATA_BY_IDENTIFIER`, we can read the As-Built
blocks from `0xDExx` with no diagnostic session/security access necessary.
I used [Online As-Built databases](https://cyanlabs.net/asbuilt-db/ ) and
various coding spreadsheets shared online to find values we might be
interested in using for fingerprinting (both vehicle parameters and
identifying the platform).
ABS:
- Payload tier (Base, Mid Payload Upgrade, Heavy Duty Payload
Upgrade...)
- Wheelbase
- Steering ratio
- Cruise Control Mode (Normal, Adaptive)
- Enable Stop and Go
PSCM:
- Enable Lane Keeping Aid
- Enable Traffic Jam Assist
- Enable Lane Centering Assist
IPMA (Q4):
- Steering ratio
- Wheelbase
APIM (Sync 3 and Sync 4):
- Steering ratio
- Vehicle weight
- Wheelbase
There are more potentially useful signals which I haven't included
although they might not be necessary:
- Vehicle (Ford platform code, like "C344" or "C519" - although the
source of the mapping from index to code is FORScan and not Ford
themselves unless we can find a better source).
- Fuel type
- Vehicle length/height/front track/rear track
- Tire circumference (could be useful for converting wheel speed rad/s
to m/s)
- Steering angle source (Pinion, Wheel)
- Country code (letters, e.g. US, CA or UK)
- Transmission type
- CAN network architecture
- More feature flags (the APIM also stores settings for ACC, LCA, BLIS)
The full list of settings I have found is
[here](https://github.com/incognitojam/op-notebooks/blob/main/ford/settings.py ).
