this is utilising REST path , append ";AllowHtapiForLargeResults=1;HTAPI_ActivationThreshold=0;"; like for other test cases which are fetching data

Summary
Adds a performance test to mimic the data-fetching flow used by SQL Server Analysis Services (SSAS) when retrieving data through the ODBC driver.
Changes
TransformDataFetchUsingSQLGetDataperformance test.all_bq_types_2integration test table containing a wide range of BigQuery data types.SQLFetch.SQLGetDatawithSQL_C_WCHAR.SQLNumResultCols.Purpose
The test is intended to reproduce the row-by-row and column-by-column ODBC data retrieval pattern observed when SSAS imports data through the driver. It provides a reproducible performance benchmark for investigating and comparing driver behavior in an SSAS-like workload.
