Windows does not support versioned symbols. Fortunately Windows also
doesn't have an exported stable ABI.

Export rte_tel_data_add_array_int -> rte_tel_data_add_array_int_24
and rte_tel_data_add_dict_int -> rte_tel_data_add_dict_int_v24
functions.

Windows does have a way to achieve similar versioning for symbols but it
is not a simple #define so it will be done as a work package later.
