REGRESSION(r208082): 1% Speedometer regression on iOS

https://bugs.webkit.org/show_bug.cgi?id=164852

Reviewed by Chris Dumez.

Source/WebCore:

Temporarily disable CEReactions entirely to recover the regression in Speedometer since
reverting r208082 wouldn't remove CEReactions from other DOM APIs and if r208082 was a regression,
then they're likely causing a regression on Speedometer as well.

* dom/CustomElementReactionQueue.cpp:
(WebCore::CustomElementReactionStack::ElementQueue::add): Removed the release assert added in r208785
since reactions can be inserted into the backup queue while the queue is running.
(WebCore::CustomElementReactionStack::ElementQueue::invokeAll): Ditto.
* dom/CustomElementReactionQueue.h:
(WebCore::CustomElementReactionStack::CustomElementReactionStack): Removed all the code so that this
constructor would be optimized away by clang.
(WebCore::CustomElementReactionStack::~CustomElementReactionStack): Ditto.

LayoutTests:

Add failing test expectations for various custom elements now that CEReactions is not working.
