Don't set document.currentScript for <script type="module">

[domenic]

Per discussions in web components F2F, we don't like this API anymore and want to consider a better one for new stuff like modules and scripts-inside-shadow-DOM.

How should the relevant events work in this case. For shadow DOM we can mark the events scoped, but that doesn't really affect to the behavior in light DOM.

beforescriptexecute and afterscriptexecute, you mean? They seem somewhat unrelated to me... modules would still have them.

[smaug----]

Don't know why those are unrelated, but anyhow, something to keep in mind at least.

@domenic I think we should not dispatch those either. I think the idea with those events is that you can then grab the script (using document.currentScript and manipulate it before it gets executed. The events are also controversial per #943 so only Gecko would implement support for them presumably...
