[Strings] stringview_*.slice (#4805)

Unfortunately one slice is the same as python [start:end], using 2 params,
and the other slice is one param, [CURR:CURR+num] (where CURR is implied
by the current state in the iter). So we can't use a single class here. Perhaps
a different name would be good, like slice vs substring (like JS does), but
I picked names to match the current spec.
