[Enhancement] Dynamic casting

[RogueMacro]

By dynamic casting, I mean to cast an object to a Type at runtime. Specifically being able to cast it to an interface that can be passed to a constructor invoked at runtime.

Something like this?

(T*)Internal.UnsafeCastToPtr(xy);

[RogueMacro]

No, not generic. I meant using a Type object. Like typeof(T)

@bfiete You could close this as dynamic casting it provided by Variants.

BaseItem item;
Item itemImpl = scope .();
Variant variant = Variant.Create(typeof(BaseItem), &itemImpl);
item = variant.Get<BaseItem>(); // or Get<Object>()
