Eliminate setTextMultiplier from the bridge.  Make Webkit just call setZoomFactor on the frame directly.

WebKit/mac:

        This patch prepares Mac WebKit to handle two different zooming modes (full page zoom and text only zoom).
        New API is added that is parallel to the text zoom public API.  You can get/set a pageSizeMultiplier and you
        can zoom the page in, out or reset it to the standard size.

        In the implementation only one zoom factor is stored, and setting one multiplier will shift you into that mode
        and set the common zoom factor.  In other words you can't combine text zoom and page zoom.  One will always
        win.
