Expose deno.ErrorKind

Originally we planned to have a JS class for each error code. But it
seems better to just have a single DenoError class with a "kind"
property. One nice thing about using an enum instead of classes for
errors is that switch() can be used during error handling instead of a
bunch of instanceof branches.
