        Make validation message bubble testable

        Introduce a setting for validation message timer so that we can configure
        how long we show a validation message bubble.

        Test: fast/forms/validation-message-appearance.html

        * html/ValidationMessage.cpp:
        (WebCore::ValidationMessage::setMessageDOMAndStartTimer):
          Don't set a timer if the timer magnification value is 0 or negative.
          Otherwise, hides the bubble length * magnification / 1000 seconds.
        * page/Settings.cpp:
        (WebCore::Settings::Settings): Initialize the timer magnification value.
        * page/Settings.h:
        (WebCore::Settings::setValidationMessageTimerMagnification): Added.
        (WebCore::Settings::validationMessageTimerMaginification): Added.
