Bug 250403

The Recorder::drawFocusRing() versions with timeOffset are not implemented. But after looking at the code, it turned out the timeOffset was never used and we always pass std::numeric_limits<double>::max() to NSInitializeCGFocusRingStyleForTime(). This means the return value of NSInitializeCGFocusRingStyleForTime()() is always false. So we do not need to pass the arguments: timeOffset and needsRepaint to drawFocusRing. Therefore the Mac versions of GraphicsContext::drawFocusRing() are not needed.

So we can have two versions only of GraphicsContext::drawFocusRing():

1. One that takes (const Path&, float outlineWidth, ...). The outlineWidth is used to set the lineWidth on Cairo and to set the blurRadius on Windows.
1. One that takes (const Vector<FloatRect>&, float outlineOffset, float outlineWidth, ...). The outlineOffset is used to shrink the focus ring rectangles. On Cocoa and Windows, this version will convert the rects to a Path and call the previous one.
