        Add processing for "in cell" mode and end tag processing for "in row"
        https://bugs.webkit.org/show_bug.cgi?id=41688

        I added several new table tests, not all of which pass yet.
        Remaining failures exist due to lack of full "in table body" mode
        support, which Adam has an outstanding patch for.
        I believe all of the various branches added by this change are
        covered now by our tests.

        * html/HTMLElementStack.cpp:
         - Added QualifiedName versions of inScope functions.
           Using tagName.localName() is wrong for non-HTML elements,
           in preparation for supporting foreign content we should centralize
           our handling of QualifiedName in these functions instead of
           sprinkling more .localName() calls around the code.
        (WebCore::HTMLElementStack::inScope):
        (WebCore::HTMLElementStack::inListItemScope):
        (WebCore::HTMLElementStack::inTableScope):
        * html/HTMLElementStack.h:
        * html/HTMLFormattingElementList.cpp:
        (WebCore::HTMLFormattingElementList::Entry::operator==):
        (WebCore::HTMLFormattingElementList::Entry::operator!=):
         - Calling element() on markers will assert, so use m_element.
        * html/HTMLTreeBuilder.cpp:
        (WebCore::HTMLTreeBuilder::closeTheCell):
         - Implemented per the spec.
        (WebCore::HTMLTreeBuilder::processStartTag):
         - Use isTableBodyContextTag where possible.
         - Add InCellMode.
        (WebCore::HTMLTreeBuilder::resetInsertionModeAppropriately):
         - Use isTableBodyContextTag where possible.
        (WebCore::HTMLTreeBuilder::processTrEndTagForInRow):
         - This code is needed from at least two callsites.
        (WebCore::HTMLTreeBuilder::processEndTag):
         - Add InCellMode and InRowMode
        (WebCore::HTMLTreeBuilder::processCharacter):
        (WebCore::HTMLTreeBuilder::processEndOfFile):
        * html/HTMLTreeBuilder.h:
