Add validation for Infinity/NaN and negative value for arc

[Homaid]

Resolves #8198

Changes:
This PR adds validation for invalid numeric values in the arc() function to prevent silent failures and improve debugging.

What was added:

• Added finite number validation for all numeric parameters (x, y, w, h, start, stop)
• Added positive value validation for width and height parameters
• Added helpful console warnings when invalid values are detected (Infinity, NaN, negative/zero dimensions)
• Function now returns early when invalid values are passed, preventing rendering errors

Console shows clear warnings for:

• Infinity values
• NaN values
• Negative width/height
• Zero width/height

PR Checklist

I think this works, but maybe let's wrap this all in an if statement that skips the check in the cases where FES is disabled. Currently I think that means checking if !p5.disableFriendlyErrors and typeof IS_MINIFIED === 'undefined' (see the setup for param validation here.)

Also cc @ksen0 -- is this the kind of thing we want to hold off on merging until after the release candidate is fully released?
