PRO-1707 Load PowertrainType from UserDevice into reports for Vehicle Data

1. add array column to available properties with the powertrain that applies to, null or empty for all
2. grpc GetUserDevice, need to add the Metadata properties to be exposed so we can get the powertrain type
3. when querying GetSignals, the denominator (ie count of all) should be based only on the powertrains impacted, this will require persisting something in signal_events_tracking so that we can know what to exclude at query time.

While we're in here it occurred to me let's also add the Protocol:
CANProtocol *string json:"canProtocol,omitempty"`` from the UserDeviceMetadata

Then also just update your local protoc to latest and regen protos
