Bug 1622229 [wpt PR 22236] - Correctly test document.all quirks, a=te…

…stonly

Automatic update from web-platform-tests
Correctly test document.all quirks

For legacy compatibility, this property is specified with some willful
violations of JS: <https://html.spec.whatwg.org/#dom-document-all>.
Prior to this commit, idlharness wasn't accounting for these, so
html/dom/interfaces.html was wrong for document.all/HTMLAllCollection
tests.

It's a bit ugly to include this directly in idlharness.js and
testharness.js, but it's the cleanest solution I can think of.

Fixes #4207.
