Thinking of adding GCODE_MACROS, anyone have use for this?

[classicrocker883]

What are your thoughts on being able to edit and run your own custom GCode from the LCD menu?

See the PR here MarlinFirmware/Marlin#28009 for more information

Basically, I was able to add a menu option that you can enter and run your own custom Gcode commands - (and view them).

I've been tinkering around and got it working to a usable state.

• A set of available Gcodes: M810-M819
• Edit, Run, View up to 10 different commands
• I'm not exactly sure if you can add multiple codes in one line, I suppose its possible
• • e.g. G28 G29 M500
• (in a way) it's almost like having a terminal inside the UI in a menu

Thoughts on what it would be like?
Is this a feature you'd like to see in this firmware?

Please let me know your thoughts, and/or suggestions.
