Remove launchScript() from Gradle bootJar and bootWar tasks

Proprietary

Spring Boot 4.0 removed support for fully executable jars and wars, so BootJar and BootWar no longer have launchScript(). Removes the statements that use it from Gradle build files, including calls with a configuration block and property-style launchScript.properties assignments. A use in the unbraced body of an if, else or loop is marked for manual migration instead.
