* Implement CORDOVA_COMPATIBILITY_VERSION_EXCLUDE and CORDOVA_COMPATIBILITY_VERSION_IOS/ANDROID
CORDOVA_COMPATIBILITY_VERSION_IOS or CORDOVA_COMPATIBILITY_VERSION_ANDROID allows to override compatibility version for a specified platform.
CORDOVA_COMPATIBILITY_VERSION_EXCLUDE provides a way of excluding a certain plugin from compatibility version calculation. You can pass several plugin names with ';'. For example: `CORDOVA_COMPATIBILITY_VERSION_EXCLUDE='cordova-plugin-crosswalk-webview;cordova-plugin-device'`
* Changes after review
