In order to be able to debug, for example, a Linux process from a macOS host, we
need to be able to initialize a ReflectionContext without Objective-C
interoperability. This patch turns ObjCInterOp into another template trait, so
it's possible to instantiate a non-ObjC MetadataReader on a system built with
ObjC-interop (but not vice versa).
This patch changes the class hierarchy to
TargetMetadata<Runtime>
|
TargetHeapMetadata<Runtime>
|
TargetAnyClassMetadata<Runtime>
/ \
/ TargetAnyClassMetadataObjCInterop<Runtime>
/ \
TargetClassMetadata<Runtime, TargetAnyClassMetadata<Runtime>> \
\
TargetClassMetadata<Runtime, TargetAnyClassMetadataObjCInterop<Runtime>>
TargetAnyClassMetadataObjCInterop inherits from TargetAnyClassMetadata because
most of the implementation is the same. This choice makes TargetClassMetadata a
bit tricky. In this patch I went with templating the parent class.

This fixes the build on Windows by fixing the template code. The template type was not qualified and caused an ambiguity in the name resolution with the local typename and the previously declared namespaced name.
