Candera/FeatStd CMake Build System Changes

Clipping Enabled by Default

The flag CANDERA_LAYOUT_CLIPPING_ENABLED was disabled by default. From now on the flag CANDERA_LAYOUT_CLIPPING_ENABLED is enabled by default. Reason: for proper layout in terms of HMI controls the clipping of layout areas is mandatory. HMI controls are a major focus of CGI Studio 3.5.
