Make MessageType impl Copy

We can make the Uuid helper type Copy, because bevy_reflect::Uuid implements Copy.
We can make the `MessageKind` type Copy after that and we can make the
`MessageType` type Copy because of that.

This is a prerequisite for changing the `ReceiverBundle::get_ids()`
function to return an iterator over a static slice, which we want to do
to reduce the number of allocations here, because allocating a
`Vec<MessageType>` is just too much ;-).
