fix(odata): skip primitive-collection NPEs on Mendix <11.0 (10.24 nightly)

`create external entities from <odata client>` bulk-imports an OData contract and,
for each Collection(Edm.X) property, creates a non-persistent entity backed by
Rest$ODataMappedPrimitiveCollectionValue / Rest$ODataPrimitiveCollectionEntitySource
(mirroring how Studio Pro handles e.g. TripPin Person.Emails). Those storage types
are a Mendix 11.0 feature and do not exist in the 10.x type cache, so writing them
made `mx check` on Mendix 10.24 abort the entire project load with:

  Mendix.Modeler.Storage.Caches.TypeCacheUnknownTypeException: The type cache does
  not contain a type with qualified name Rest$ODataMappedPrimitiveCollectionValue.

(The 10.24 nightly failed 10-odata-examples on both engines for this reason.)

Pre-11 Studio Pro simply omits OData primitive-collection properties when importing
an external entity, so mirror that: gate createPrimitiveCollectionNPEs behind
ProjectVersion().IsAtLeast(11, 0) and log a skip line on older projects. The rest
of the external entities still import normally, so 10.24 keeps its external-entity
coverage. On 11.x the NPEs are created exactly as before.

Verified with the doctype gate: 10-odata-examples now passes on Mendix 10.24
(both engines) and still passes on 11.12 (NPEs created).
