386947-1.xul, now has one assertion since we take a different code
path with chrome URL's and XBL files. The assertion is triggered since the
binding is invalid.

In Notify(), we should guarantee that the inner window we get is for the
document, and avoid using null outer window pointer.

We can use the unattach shadow stuff because BlastSubtreeToPieces will remove
all the slots.

This patch removes the following functions:
* nsContentUtils::IsCustomElementsEnabled()
* CustomElementRegistry::IsCustomElementEnabled(JSContext* aCx, JSObject* aObject)
* CustomElementRegistry::IsCustomElementEnabled(nsIDocument* aDoc)
and all references of the pref.

This patch removes the dom.webcomponents.shadowdom.enabled pref and all its
references, including the following functions:
* nsContentUtils::IsShadowDOMEnabled()
* nsIDocument::IsShadowDOMEnabled()
* nsDocument::IsShadowDOMEnabled(JSContext* aCx, JSObject* aGlobal)
* nsDocument::IsShadowDOMEnabled(const nsINode* aNode)
* nsTextNode::IsShadowDOMEnabled(JSContext* aCx, JSObject* aObject)
This function is renamed and updated to nsDocument::IsCallerChromeOrAddon():
* nsDocument::IsShadowDOMEnabledAndCallerIsChromeOrAddon(JSContext* aCx, JSObject* aObject)
I didn't change the tests that load Shadow DOM tests in an iframe, in the interest of keeping hg annotation history.

As expected, this is specific to the UA widget stuff.
What's going on here is that given we don't clear out the host when unattaching
the shadow tree, mutating that shadow tree still notifies all the way up to the
document, and that gets all the other code confused, thinking that the node is
connected.
Indeed, the first assertion that fails when loading that test-case in a debug
build is:
https://searchfox.org/mozilla-central/rev/17f55aee76b7c4610a974cffd3453454e0c8de7b/dom/base/nsNodeUtils.cpp#93
This seems the best fix to avoid confusion. Also clear the mutation observer,
to completely forget about the host.
Chrome code dealing with UA widgets needs to be careful, but I think this is
safe. All the code that assumes that GetHost() doesn't return null is in code
dealing with connected shadow trees only (style system / layout), or in
mutation observer notifications from the host.

Allows top level non-XUL documents to share this code. Three tests had to
be adjusted to account for the attributes being chrome only now and not
available to content privilege XUL. In two tests, the values attributes
are now simply undefined. The crashtest was converted to a chrome
mochitest to preserve what it was testing.

This is sound because the unlink implementation of the stylesheet drops the
preserved wrapper, and there are no strong references back to any node from the
stylesheet or any of the non-unlinked members.
This almost is the same setup that works for document sheets. We need to account
for a double reference in case the sheet is applicable because Servo keeps
another reference to it in that case, instead of in the StyleSet / PresShell.
Added the testcase as a crashtest, in the hopes that if it regresses leak
reporting on automation will catch it.

Most of the Shadow DOM related code are behind "dom.webcomponents.enabled" and
this pref is only used by Shadow DOM right now, so we should rename it to
"dom.webcomponents.shadowdom.enabled"
