Caching of reflection data

[Beider]

The MDFramework relies heavily on reflection, however reflection is rather slow. This is particularly apparent inside

MDGameInstance.RegisterNewNode(Node Instance)

To solve this problem a reflection data cache should be added, preferably this should be hidden inside MDStatics / MD*Extensions and be used across the entire framework. It would also be good if this cache was accessible for the people who use the framework so they can use the same cache for their own reflection needs.

A few followups to this,

• No need to look for MdAutoRegister or bind nodes on anything in godot namespace
• Add a way to pre-cache your classes so you can do it on your game loading screen.

An idea for precaching would be to have a few methods like,

// Precahce just the given type
this.GetMDReflectionCache().PreCahceType(type);

// Precache the list of types
this.GetMDReflectionCache().PreCahceTypes(List<Type>);

// Precahce everything in a namespace
this.GetMDReflectionCache().PreCahceTypesInNamespace(string namespaceName);
