Auto merge of #18870 - servo:cast, r=KiChjang

Use pointer casts instead of tramsutes to raw::TraitObject

Casting `*const T` to `*const U` with `U: Sized` is allowed even if `T: ?Sized`. This safely extracts the data pointer out of a trait object, without relying on the memory representation of trait objects.
