Remove obsolete isJava8Compatible() checks from Gradle files

Since the project now requires JDK 8+, the JavaVersion.current().isJava8Compatible() checks are no longer needed. This commit removes those checks and unconditionally includes jme3-lwjgl3 and jme3-saferallocator modules in settings.gradle, and unconditionally applies the Xdoclint:none javadoc option in all subprojects.
