Extend ReflectiveClassBuildItem with queryPublicMethods option

Configures whether declared methods should be registered for reflection,
for query purposes only, i.e. {@link Class#getMethods()}. Setting this
enables getting all declared methods for the class but does not allow
invoking them reflectively.
