Editorial: Update uses of WebIDL "invoke a callback function"

[jeremyroman]

It's now required for non-promise-returning uses to specify how exceptions are handled. Specifying the argument list is also made more consistent, using the shorthand syntax for lists where appropriate.

Part of whatwg/webidl#1425.

@domenic ptal?

I fixed some missing quotes, tweaked some nearby stuff for the events case, and made some more wording uniform. I also did one case you missed, the custom element callback reactions.

As such, I'd like to ask for review of my commit from you, and thne we can merge :)

Split a run-on sentence in the note, as it had gotten a little unwieldy. Not sure how I missed the custom element reactions one in the final version; must have hit undo one too many times at some point, or something.
