        Some editing cleanup

        No change in functionality.

WebCore:
        * editing/TextIterator.cpp:
        (WebCore::plainText):
        * editing/TextIterator.h:
        Made WebCore::plainText() return String instead of DeprecatedString.

        * bridge/mac/WebCoreAXObject.mm:
        (-[WebCoreAXObject textUnderElement]):
        (-[WebCoreAXObject value]):
        (-[WebCoreAXObject doAXBoundsForTextMarkerRange:]):
        (-[WebCoreAXObject doAXNextSentenceEndTextMarkerForTextMarker:]):
        (-[WebCoreAXObject doAXPreviousSentenceStartTextMarkerForTextMarker:]):
        Updated for the above change. There is no need to explicitly convert to NSString now.

        * editing/EditCommand.cpp:
        (WebCore::EditCommand::EditCommand): m_startingSelection and m_endingSelection are actually
        initialized in constructor body, so the work done in initializer list was wasted.

        (WebCore::EditCommand::apply): Moved some stars.
        (WebCore::EditCommand::unapply): Ditto.
        (WebCore::EditCommand::reapply): Ditto.
        (WebCore::EditCommand::setStartingSelection): The loop exit condition was evaluated twice,
        removed one of the checks.

        * editing/SelectionController.cpp:
        (WebCore::SelectionController::toString): plainText() result type now matches what we need here.

        * page/mac/WebCoreFrameBridge.h:
        * page/mac/WebCoreFrameBridge.mm:
        Removed unused -[WebCoreFrameBridge deleteKeyPressedWithSmartDelete:granularity:] and
        -[WebCoreFrameBridge forwardDeleteKeyPressedWithSmartDelete:granularity:].

WebKit:
        * WebView/WebHTMLView.mm:
        (-[WebHTMLView deleteToEndOfLine:]):
        (-[WebHTMLView deleteToEndOfParagraph:]):
        WebCore had a duplicate of the same logic already. We are passing a boundary value to
        a function that expects granularity, this may need to be straightened out in the future.
