[fastcall] Swap the template arguments in CopyAndConvertArrayToCppBuffer

For CopyAndConvertArrayToCppBuffer<T, type_info>(src, dst, length),
type `T` can be deducible from `dst`, but `type_info` cannot be
deducible so it's better to rewrite it as
CopyAndConvertArrayToCppBuffer<type_info, T>(src, dst, length).
