[C++][FlightRPC] Arrow Flight timeout test failure on MSVC Windows

[alinaliBQ]

Describe the bug, including details regarding any error messages, version, and platform.

Arrow flight tests have timeout failure on MSVC Windows after the tests finish running and are passing. This is caught in MSVC Windows CI for ODBC in cpp_extra.yml. This behavior is not observed in MinGW Windows.

Link to log run: https://github.com/apache/arrow/actions/runs/22742119641/job/65957707054?pr=49402.

The full log shows all tests passing, here is simplified output:
