Improve comparison of intervals in SVGSMILElement::resolveFirstInterval

For open-ended intervals such as [3) - i.e. begin=3s and end/duration/etc
unspecified - every call to resolveFirstInterval() would think that a new
interval had been created, and notify/require a reschedule of the
animations.
Add a new type SMILInterval and a suitable operator for that, and then
use it to compare the raw values (i.e. if both endpoints are exacly the same.)
