Add attribute to Local-Only Methods

[tismatis]

Feature Description:
Possible to add an custom attribute only for UdonSharp like [NonNetworked] that will renames internally the functions with an _ in front like MyNonNetworkedMethod() into _MyNonNetworkedMethod() ?

I've modified UdonSharp to experiment with this but the main issue is that it's a lot more complicated than simply just handling the method name, since you need to change all nameof's as well, and those can even be used as defaults for serialized fields.

Yep, I checked myself before create the issue and I didn't really understand how I should implement it myself because I don't know how UdonSharp compiles xd

If I implement this, it'll mangle the internal method name so you you can't use the events with SendCustomEvent. Udon 2 fixed this more properly and it seems like Soba carried over that part at least.
