Tuples don't get `ReflectFromReflect` type data registered in `GetTypeRegistration`

Bevy version

0.15.1

Summary

i.e.

registry.register_type::<(usize,usize)>();

will not register a ReflectFromReflect type data against the tuple.

for it to take, you have to manually do it via:

registry.register_type_data::<usize, ReflectFromReflect>

This means if I want to construct arbitrary types like:

stuct MyStruct {
    pub foo: (usize,usize)
}

I have to always do that manual registration

Unfortunately this might be difficult to do since we want GetTypeRegistration to work even if not all tuple fields are FromReflect. But in order to register ReflectFromReflect automatically, we have to add the FromReflect bound.

We'd need something like specialization or just flat out require FromReflect on tuples.

Ahh.. figured there was a good reason!

If I had a penny every time I wished specialization was a thing, I'd be rich!
