Descrizione
### Describe the bug, including details regarding any error messages, version, and platform.
We (Deephaven Data Labs) have a simple FlightSQL implementation that doesn't support PreparedStatement with the understanding that executing ad hoc queries should be possible with JDBC's Statement.execute()/executeQuery(). However, the following test case failed with an exception that indicates the driver chooses to use PreparedStatement anyways. Note that the ADBC driver for FlightSQL (Python) uses CommandStatementQuery for the same use case.
```java
@Test
public void testJDBCExecuteQuery() throws SQLException {
try (Connection connection = DriverManager.getConnection("jdbc:arrow-flight-sql://localhost:" + localPort +
"/?Authorization=Anonymous&useEncryption=false")) {
Statement statement = connection.createStatement();
ResultSet rs = statement.executeQuery("SELECT * FROM crypto where Instrument='BTC/USD' AND Price > 50000 and Exchange = 'binance'");
ResultSetMetaData rsmd = rs.getMetaData();
int columnsNumber = rsmd.getColumnCount();
while (rs.next()) {
for (int i = 1; i <= columnsNumber; i++) {
if (i > 1) System.out.print(", ");
String columnValue = rs.getString(i);
System.out.print(columnValue + " " + rsmd.getColumnName(i));
}
System.out.println("");
}
}
}
```
```

This Python script runs OK against the same server.
```Python
with adbc_driver_flightsql.dbapi.connect("grpc://localhost:10000",
conn_kwargs={ "adbc.flight.sql.rpc.call_header.authorization": "Anonymous"}) as conn:
with conn.cursor() as cursor:
cursor.execute("SELECT * from crypto")
pa_table = cursor.fetch_arrow_table()

Riprodurre FlightSqlTest.testJDBCExecuteQuery e ispezionare lo stack da AvaticaStatement.executeQuery passando per ArrowFlightMetaImpl.prepareAndExecute fino a ArrowFlightSqlClientHandler.prepare. Confrontare il percorso JDBC Statement con l’operazione Flight SQL utilizzata dall’esempio Python. Il lavoro è completato quando Statement.executeQuery() e Statement.execute() funzionano con un server senza supporto per PreparedStatement.
