        Chromium Mac: Fork ScrollAnimatorMac to ScrollAnimatorChromiumMac for overlay scrollbar support
        https://bugs.webkit.org/show_bug.cgi?id=59753

        No new tests. Just forking ScrollAnimatorMac to ScrollAnimatorChromiumMac.

        * WebCore.gyp/WebCore.gyp: Added IntPointMac.mm. This is used by some functions in ScrollAnimatorChromiumMac. Also added filters for conflicting class names in ScrollAnimatorChromiumMac.
        * WebCore.gypi: Added ScrollAnimatorChromiumMac.h/mm.
        * platform/ScrollAnimator.cpp: Extended the #ifdef around ScrollAnimator::create() so that the chromium version will be created.
        * platform/chromium/ScrollAnimatorChromiumMac.h: Added.
        (WebCore::ScrollAnimatorChromiumMac::setIsDrawingIntoLayer):
        (WebCore::ScrollAnimatorChromiumMac::isDrawingIntoLayer):
        (WebCore::ScrollAnimatorChromiumMac::haveScrolledSincePageLoad):
        * platform/chromium/ScrollAnimatorChromiumMac.mm: Added. Forked from ScrollAnimatorMac and replaced all instances of ScrollAnimatorMac with ScrollAnimatorChromiumMac and ScrollbarThemeMac with ScrollbarThemeChromiumMac. Removed the ENABLE(SMOOTH_SCROLLING) around the file. Stubbed out ScrollAnimatorChromiumMac::scroll() if smooth scrolling is disabled.
