Change GetInfo disabled tests to start new connection

[alinaliBQ]

Changed tests TestSQLGetInfoCatalogLocation, TestSQLGetInfoDropSchema, and TestSQLGetInfoDropTable to start a new connection, this fixes the test failures.

This PR fixes:

[  FAILED  ] ConnectionInfoTest/0.TestSQLGetInfoDropSchema, where TypeParam = arrow::flight::sql::odbc::ConnectionInfoMockTest
[  FAILED  ] ConnectionInfoTest/0.TestSQLGetInfoDropTable, where TypeParam = arrow::flight::sql::odbc::ConnectionInfoMockTest
[  FAILED  ] ConnectionInfoTest/1.TestSQLGetInfoCatalogLocation, where TypeParam = arrow::flight::sql::odbc::FlightSQLODBCRemoteTestBaseis the result.

Note that the other cases of ConnectionInfoTest/1.TestSQLGetInfoDropSchema, ConnectionInfoTest/1.TestSQLGetInfoDropTable, and ConnectionInfoTest/0.TestSQLGetInfoCatalogLocation pass successfully.

The root cause is inside flightsql-odbc code. Raised apache#49482 for a permanent fix for the ODBC driver, so the tests may pass with global connection as well.
