Improve led usage

[optozorax]

• Fix usage of macro ML_LED_*
• Add option to disable default layer indicating on leds

Or I think, it is better to move code in DISABLE_DEFAULT_ML_LEDS_LOGIC block into auto-generated code in layer_state_set_user in keymap.c for Oryx. But this is bad from backward compatibility point...

Thank you for the input!

However, we would like to keep things consistent between the different keyboards (eg, same style of defines, same defaults, etc).

I have a PR upstream to update a number of aspects of the boards. And have included the option to turn off or disable the LED indicators (qmk#10119 if you are interested). And we'd prefer to get that merged upstream first, and then applied to our repo.

Thank you! I see MOONLANDER_USER_LEDS in this PR, so I can close this merge request.
