Ensure forward progress in SVGSMILElement::ResolveInterval

With some unlucky combinations of parameters (timing and current time),
we could end up spinning in the resolve loop, (re)resolving the same
interval over and over, not making forward progress.
Guard against this by bumping the next "begin after" value by epsilon if
the resolved end is the same as the current "begin after".
