SCUMM: UB & type system undermining in save/load code

Description

The SCUMM engine save/load code triggers UB by trying to get the offsets of non-POD members, and subverts the type system by casting to void * during serialisation. Already I found one bug in SCUMM HE where a SpriteInfo** was being treated as SpriteInfo* for game versions < 64, and this was compiling even though it is wrong because it was getting passed into a parameter of type void *. So all this needs to be fixed to use the Common::Serializer and to stop using void *.
