Support Standard Structure Exceptions about wing

[Chriscbr]

Thanks for opening the issue Asher. I think the right way to model errors in Wing is still an open question, and the solution might depend on how we might want to support runtime interop with other languages in the future. Right now you can only throw and catch strings in Wing but I'm not sure this is robust enough.

Complex hierarchies of exceptions like those sometimes found in Java or Python can sometimes be tedious and add a lot of mental overhead for folks learning languages in my opinion. That said, there are many cases where it's handy to be able to check for a specific type of error raised by a library or function. I think Wing could benefit from a more well-defined error type that has a simple interface (like storing a message and a stack trace, perhaps). Since Wing doesn't have a convention of functions returning "result" types like Rust, I want to say that Golang's error handling could be worth looking for as inspiration.
