feat: Asset references, world.get_asset and world.has_asset bindings

[aggyomfg]

Hello, thanks for your creation! BMS is very useful engine!

This PR Potentially close #479

New Asset Reference Type: Added ReflectBase::Asset(UntypedHandle, ComponentId)
Asset Creation Functions: Added ReflectReference::new_asset_ref() and ReflectBaseType::new_asset_base()

Added two new world functions:
get_asset(handle_reference, registration) - Retrieves an asset by handle
has_asset(handle_reference) - Checks if an asset exists

Tests, Docs + but didnt get what else needed, please ask.
