Redesign VisualScriptYield

[Gallilus]

Describe the project you are working on

VisualScript plugins and usability

Describe the problem or limitation you are having in your project

VisualScriptYield is not working. More info in PR https://github.com/godotengine/godot/pull/48687 Now that GDscript2.0 uses await it seems outdated and in need of a rework anyway.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

re-evaluate. visual_script_yield_nodes.cpp visual_script_yield_nodes.h

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

I do not know the details around await to make this judgment.

If this enhancement will not be used often, can it be worked around with a few lines of script?

I see no workaround. Its best that VisualScript and GDScript are as similar as possible to remove confusion.

Is there a reason why this should be core and not an add-on in the asset library?

await is core in GDscript.
