Refactor testing condition in conanfile.py

The testing condition repeated across the script was abstracted into a property, _run_tests. This change simplifies the condition check for running tests, and specifically handles a case where the apple-clang compiler version is less or equal to version 14.

Contributes to CURA-10561
