Revert 202146 "Don't allow whitespace between elements with disp..."

Looks to be breaking the build:

c:\b\build\slave\win_stable\build\src\third_party\webkit\source\core\dom\text.cpp(259) : error C3861: 'isHTMLTableCellElement': identifier not found


> Don't allow whitespace between elements with display:table-cell
> 
> In https://codereview.chromium.org/1065563005 we started allowing whitespace
> inside anonymous table cells. We're only interested in anonymous table cells
> that were generated to contain non-table-part content. If the anonymous cell
> was generated to contain a form element with display:table-cell, for example, then
> that is not a situation where we want to treat any whitespace before and
> after the form element as renderable.
