Fix PQdescribePrepared with more than 7498 params

If a query has more than 7498 params, the ParameterDescription message
exceeds the 30000 byte limit on messages that are not specifically
marked as possibly being longer than that (VALID_LONG_MESSAGE_TYPE).
To fix, add ParameterDescription to the list.
