slog: add Level.MarshalJSON

Add a MarshalJSON method to Level so that it
marshals as a string.

This lets us remove special cases for Level in the handlers.

It also ensures that others who write handlers that output JSON will
get strings instead of numbers; the numbers are obscure,
uninformative, and could be confused with the values of other
level-numbering schemes.

Also, improve handler tests to check replacement.
