Subject: [PATCH 2/8] Fix Primitive Collection serialization

This was broken by both #5871 and #5682:
1. When a List<Guid> was serialized, it was recognized as a primitive collection and thus plainly written to the JSON without any type information: ["d4d8404c-4357-47ff-a343-649a116539f5"]
2. When this JSON was deserialized, due to lack of type info, it was deserialized as List<object>, containing strings. This is already not good.
3. When this List<object> gets serialized again (e.g. due to multiple workflow suspends causing WorkflowState serialization), this time it fails the primitive collection recognition, because object is not a primitive type. It now gets serialized as {"_items": ["d4d8404c-4357-47ff-a343-649a116539f5"], "_type": "Object[]"}
4. When that JSON gets deserialized, it tries to ReadType() but ReadType() fails to parse Object[] since it lacks the logic from TypeJsonConverter to throw away the [] before looking up Object in the WellKnownTypeRegistry, so it returns null as a type. Without a type but being faced with a json object { ... } it now deserializes into an ExpandoObject
5. Any further serialization / deserializations will now cause the expando object to get nested deeper and deeper every time.

Subject: [PATCH 4/8] Fix C# Script<T> race conditino

Compilation of the Script wasn't entirely thread safe, specifically, if the same script was being evaluated twice at the same time on an empty cache:
Thread 1: Puts Script<T> into cache, then starts compiling it
Thread 2: Finds not yet compiled Script<T> in cache, starts compiling it as well
Thread 1: Done compiling, Assembly.Load it for running
Thread 2: Done compiling, Assembly.Load it <--- Exception: Assembly with name XYZ already loaded

The Solution is to use CreateDelegate which compiles the script the moment it is being put into the cache and the cache then only serves precompiled delegates that are immediately runnable.
