major(cb2-16760): added new test type schema and renamed test-result-test-type

[cb-cs]

Add Test Type Schema to Types Definition Package

CB2-16760

Changelog

• added new top level enums directory for what will eventually contain all of the shared enums
• refactored v1/test-type to v1/test-result-test-type as that definition is what a test-result submits as an object in the testTypes array on a test-result, rather than what is returned by the test-types-service.
• moved vehicleConfiguration.enum.ts to the top level enum directory (only being used by types-service currently)
• created test-type directory which corresponds to the object returned by the test types service
• implemented new plugin that now generates the correct references when generating json-schemas
