genex-LINK_(LIBRARY|GROUP) features: update variables behavior

Browse Source 
Variable CMAKE_LINK_(LIBRARY|GROUP)_USING_<FEATURE>_SUPPORTED is evaluated
only if CMAKE_<LANG>_LINK_(LIBRARY|GROUP)_USING_<FEATURE>_SUPPORTED is not defined.

This new behavior enable to activate a feature globally on a platform and to disable
it for some compilers and languages.
