Add new DefaultBinding(Binding<T, U>) constructor

[lukaseder]

The org.jooq.impl.DefaultBinding type is currently used for 3 purposes:

• As a namespace for all internal bindings
• As a legacy implementation for DefaultBinding(Converter<T, U>) (now deprecated)
• As a default implementation for other bindings that delegate to an internal delegate

That last bit could be useful for users as well. We have a lot of DefaultXYZ types that wrap a delegate object and delegate to the latter by default, on all methods.

For example, users can now write:

class AlwaysInlineBinding<T> extends DefaultBinding<T, T> {
    public AlwaysInlineBinding(DataType<T> type) {
        super(DefaultBinding.binding(type));
    }

    @Override
    public void sql(BindingSQLContext<T> ctx) throws SQLException {
        ctx.render().visit(inline(ctx.value()));
    }
}

And now use that binding like any other binding, but it will only ever inline all bind values
