servo: Merge #5502 - Remove the unsafe impl Send for ConstellationControlMsg (from Ms2ger:impl-send); r=jdm

This impl made it possible to put raw pointers in ConstellationControlMsg and
send them across threads without considering the consequences.

This required making SmallVec1<T> Send if T is Send.
