ecschema-metadata does not pull KOQ from base properties if not defined in a property override

[ColinKerr]

The C++ ECObjects implementation gets the base KOQ if not defined locally: https://github.com/iTwin/imodel-native/blob/0598b2eb063f79e42141b2c5692db7df4c34a07f/iModelCore/ecobjects/src/ECProperty.cpp#L916

The TypeScript code does not:

itwinjs-core/core/ecschema-metadata/src/Metadata/Property.ts

Line 72 in 1840331

public get kindOfQuantity(): LazyLoadedKindOfQuantity | undefined { return this._kindOfQuantity; }

Ensure that serialization does not serialize base KOQ when serializing property override.

Review C++ for other property attributes that are pulled from base property if not locally defined and ensure TypeScript does the same. Make sure there are tests on both sides that ensure attributes pulled from base properties are not serialized with property overrides
