Overview

The legacy TBB module we provide has hardcoded checks for msvc versions and do not recognize 2026.

Details

We should probably just remove those checks as MSVC is a lot more stable than it used to be, and the older versions that we WAR are likely unsupported by CCCL. Investigate and either update or drop the checks.

NVBug 5781581.
