allow passing shape resource to RayCast2D and RayCast3D

[Shadowblitz16]

Describe the project you are working on:
spaceship game

Describe the problem or limitation you are having in your project:
I'm trying to make a beam weapon that stops when it hits a object
currently I am using two RayCast2D's but these things are 1 dimensional so they don't cover the whole width of my beam.
this allows things to pass through in the gaps between the raycasts

Describe the feature / enhancement and how it helps to overcome the problem or limitation:
basicly RayCast2D and RayCast3D nodes would allow passing a shape resource.
this would change the ray from a 1 dimensional ray to a 2 or 3 dimensional ray

Describe how your proposal will work, with code, pseudocode, mockups, and/or diagrams:

If this enhancement will not be used often, can it be worked around with a few lines of script?:
idk how often this would be used but I would assume or something like what I want it for it would be used alot.

also I don't think it can be actually done or at least not in a easy way.

Is there a reason why this should be core and not an add-on in the asset library?:
other game engines like unity has it

Mostly yes, see my proposed implementation at #72 (comment).

#72 can benefit from renaming, but this proposal has a diagram at least. 🙂

I have created my own proposal regarding this, because I have some specific implementation details which might be worth discussing separately: #710.

Meta: Note that different proposals can be deemed as individual use cases (but some proposals are actually requests?).
