[selection-api] Make offset and allowPartialContainment arguments optional (#66)

These are already optional in Blink and WebKit. It's possible that it
would be web compatible to make them required, but given that the
methods still make some sense with these arguments optional, it doesn't
seem worth risking any breakage at all to find out.
