Fixes broken correspondences between html and htmlimpl. That in turn fixes
a bunch of missing MDN docs.

Jacob, this addresses your email about why html.Element is missing a bunch of
stuff.

Does this mean we're now printing warnings like "No DOM type corresponds to
ChildrenElementList"?

There are a few warnings:

Warning: no dart:dom type matches dart:htmlimpl FlagsWrappingImplementation
Warning: no dart:dom type matches dart:htmlimpl
NavigatorUserMediaErrorWrappingImplementation
Warning: no dart:dom type matches dart:htmlimpl
NavigatorUserMediaSuccessCallbackWrappingImplementation
Warning: no member Window.getComputedStyle
Warning: no member Window.getComputedStyle
Warning: no member OverflowEvent.initOverflowEvent

But much fewer than there were before were I think every correspondence between
html and htmlimpl was broken.
