[fix](gson) Fix Expr deserialize compatibility (#38799)
Since GsonBuilder.create() adds all registered factories to GSON in
reverse order, and ExprAdapterFactory is registered before the
RuntimeTypeAdapterFactory for Expr, ExprAdapterFactory will not be
executed.
This PR adjusts their registration order. Now, it will first check-in
ExprAdapterFactory whether to use the pre-134 deserialize method and
then attempt to use the RuntimeTypeAdapterFactory for Expr.class.
