Initial definition of data types and enumerations for OBD2-compatible diagnostic properties
This commit defines a list of properties that we want to support in VHAL for the purpose
of gathering vehicle diagnostics, and a data structure to contain the values of those
properties in the form of a "snapshot"
It does not yet define the property itself as that relies on a yet undefined hybrid type
Test: build
