Avoid ForceHorriblySlowRectMapping in RenderInline::clippedOverflowRectForPaintInvalidation()

Avoid ForceHorriblySlowRectMapping in RenderInline::clippedOverflowRectForPaintInvalidation()

ForceHorriblySlowRectMapping was needed in RenderInline::
clippedOverflowRectForPaintInvalidation() to avoid errors when calling
containingBlock->mapRectToPaintInvalidationBacking() with the provided
paintInvalidationState.

Now call RenderInline's own mapRectToPaintInvalidationBacking() instead
of containingBlock's to make paintInvalidationState applicable and
reduce duplicate code.

typos in description: "exsisting" and "containeingBlock"

The change seems great, but I'd feel a lot more confident after this had gone
through the bots.
