This removes the requirement that BeforeSetAttr comes before AttributeWillChange
(which needs the preparsed new value).

Bug 1259889 Part 2 [1] cannot be reverted cleanly, so I manually undo those
changes in this patch. That is, remove the ability for html.css to
invalidate dynamically since it was added specifically for details element.
Although reftest-stylo.list explicit mentions "DO NOT EDIT!", but I still
remove details pref from the file, since it doesn't harm to edit it anyway.

Add ontoggle event handler, and dispatch toggle events to the details
element if the open attribute is added or changed. According to the
spec, if a new toggle event has been queued, previous toggle events
should be aborted.

To retain backward compatibility, <details> tags should not collapse its
children when dom.details_element.enabled = false.
