fix: Use namespaced GTest targets in arrow_flight tests

[jkhaliqi]

Description

Fixed CMake linking error in Arrow Flight connector tests by using namespaced GTest imported targets (GTest::gtest,
GTest::gtest_main) instead of plain library names (gtest, gtest_main).

Motivation and Context

The Arrow Flight connector tests were failing to link with the error ld: library 'gtest' not found because the CMakeLists.txt was using old-style plain library names instead of modern CMake imported targets. This prevented building Presto with -DPRESTO_ENABLE_ARROW_FLIGHT_CONNECTOR=ON.

Impact

Test Plan

• Built Presto with -DPRESTO_ENABLE_ARROW_FLIGHT_CONNECTOR=ON
• Verified that presto_flight_connector_test executable links successfully
• Confirmed tests compile without linker errors

Reviewer's Guide

Updates the Arrow Flight connector test CMake configuration to link against the modern, namespaced GTest imported targets instead of raw library names, fixing linker errors when building with the Arrow Flight connector enabled.

File-Level Changes

Change	Details	Files
Switch Arrow Flight connector test target to use namespaced GTest imported targets to resolve linker errors.	Updated the target_link_libraries list for the presto_flight_connector_test executable to replace raw gtest and gtest_main entries with GTest::gtest and GTest::gtest_main. Ensured that the test executable now links against the CMake-provided GTest imported targets consistent with modern CMake usage.	presto-native-execution/presto_cpp/main/connectors/arrow_flight/tests/CMakeLists.txt
