Implement MemberInfo, FieldInfo, TypeInfo.DeclaredFields

Rename Type to TypeInfo
Add TypeInfo.CSharpName
Implement some generic types/parameters
Implement arrays
Remove obsolete Il2CppType.GetTypeFromTypeIndex
Implement enhanced Il2CppReflector.GetTypeFromTypeIndex (can create array and generic types on-the-fly from Il2CppType usages)
