Reland 20962 "Break cyclic reference between utils and platform."

Don't use OS::MemCopy in BitCast. It's crucial that the compiler can
optimize the memcpy away.

>  Platform includes utils.h for the definition of Vector<>, so utils.h
>  can't include platform.h and has to use memcpy instead of OS::MemCopy.
>
>  We split out Vector<> into its own header to break this cycle
>  dependency.
