Additional context

Add any other context about the problem here.

Originally added in #221370, the ability to build OpenCV with LTO is controlled by the enableLto setting. However, the corresponding flag passed to CMake did not actually enable or disable LTO!

In #339619, the flag handling was reworked (moving away from a custom helper function and to the new cmake* family of functions in lib) and this issue was discovered.
