Add support for providing default querydsl bindings

[marceloverdijk]

I would like to be able to provide default querydsl bindings for all @QuerydslPredicate being used.

You could think about excluding unlisted properties by default or add default behaviour for certain types.

Of course it should still be possible to provide a custom QuerydslBinderCustomizer via the @QuerydslPredicate but it should also apply the default bindings.

Something like this:

public class QuerydslWebConfig extends QuerydslWebConfiguration {

    @Bean
    public QuerydslBindingsFactory querydslBindingsFactory() {
        return new QuerydslBindingsFactory(SimpleEntityPathResolver.INSTANCE, defaultBindings());
    }

    public QuerydslBinderCustomizer<?> defaultBindings() {
        return new QuerydslBinderCustomizer<?>() {
            
            @Override
            public void customize(final QuerydslBindings bindings, final EntityPath root) {
                bindings.excludeUnlistedProperties(true);
                bindings.bind(String.class).first((StringPath path, String value) -> {
                    // default logic for String type.
                });
            }
        };
    }
}

Sorry for the long radio silence. We decided to follow a slightly different approach, see #2292.
