Increase the example services in VSC catalog

[gunnarx]

We discussed complementing the technical work on the IDL with focusing on describing more examples of standard services.
... the purpose being to show the value of this work through showing the end result of common service/API descriptions.

• HVAC
• Seats
• Tuner AM/FM
• SOTA
• Remote door unlock
• Vehicle tracking

Some of these may be good examples to exemplify how service descriptions may interoperate with VSS signals (including actuators that are expected to be "target value" when written).
