Define the enable function in BindingsPropertiesProcessor

[lucky8987]

Define the enable function in BindingsPropertiesProcessor like this:

/**
 * An interface for types that transform the contents of a {@link Bindings} into properties for injection into a
 * {@link org.springframework.core.env.PropertySource}.
 */
@FunctionalInterface
public interface BindingsPropertiesProcessor {

    /**
     * Transform the currently accumulated {@link Bindings}-related properties.
     *
     * @param environment the {@link Environment} that the processor is executing with.
     * @param bindings    the {@code Bindings} exposed to the application.
     * @param properties  the currently accumulated properties.
     */
    void process(Environment environment, Bindings bindings, Map<String, Object> properties);
    
    /**
     * Whether it is enabled the processor.
     * @param environment the {@link Environment} that the processor is executing with.
     * @return if true the to execute process.
     */
    default boolean enable(Environment environment) {
        return true;
    }

}

Processing the verification operations coupled in the process through the enable function is more reasonable in design, and the implementation of subclasses will also be more elegant.
