Revert 93001 - Apple-style-span class seems unnecessary
https://bugs.webkit.org/show_bug.cgi?id=12248

Reviewed by Justin Garcia.

Source/WebCore: 

Stop generating span or font elements with class="Apple-style-span" given WebKit's editing component
no longer depends on Apple-style-span since r92823 removed the dependency of copy and paste code on
style spans. WebKit continues to recognize Apple style spans to remove them.

Also renamed isSpanWithoutAttributesOrUnstyleStyleSpan to isSpanWithoutAttributesOrUnstyle*d*StyleSpan.

* editing/ApplyStyleCommand.cpp:
(WebCore::isLegacyAppleStyleSpan): Renamed from isStyleSpan.
(WebCore::isSpanWithoutAttributesOrUnstyledStyleSpan): Renamed from isSpanWithoutAttributesOr*Unstyle*StyleSpan.
(WebCore::createFontElement): No longer adds class="Apple-style-span".
(WebCore::createStyleSpanElement): Ditto.
(WebCore::ApplyStyleCommand::applyRelativeFontStyleChange): Calls isSpanWithoutAttributesOrUnstyleStyleSpan
instead of isUnstyledStyleSpan since there won't be any Apple style spans.
(WebCore::dummySpanAncestorForNode):
(WebCore::ApplyStyleCommand::cleanupUnstyledAppleStyleSpans): Ditto.
(WebCore::ApplyStyleCommand::removeEmbeddingUpToEnclosingBlock): Ditto.
(WebCore::ApplyStyleCommand::removeImplicitlyStyledElement):
(WebCore::ApplyStyleCommand::removeCSSStyle):
* editing/ApplyStyleCommand.h:
* editing/EditingStyle.cpp:
(WebCore::EditingStyle::removeStyleFromRulesAndContext): Ditto.
* editing/ReplaceSelectionCommand.cpp:
(WebCore::ReplaceSelectionCommand::removeRedundantStylesAndKeepStyleSpanInline): Calls isLegacyAppleStyleSpan instead
of isStyleSpan.
(WebCore::handleStyleSpansBeforeInsertion): Ditto.
(WebCore::ReplaceSelectionCommand::handleStyleSpans): Ditto.
(WebCore::ReplaceSelectionCommand::doApply): Ditto.
* editing/markup.cpp:
(WebCore::StyledMarkupAccumulator::appendStyleNodeOpenTag): No longer adds class="Apple-style-span".

LayoutTests: 

Rebaselined the tests because spans in these tests lost no longer have class="Apple-style-span".
