Ref-ify TextIterator API.
<https://webkit.org/b/139823>

Reviewed by Antti Koivisto.

Source/WebCore:

Change TextIterator functions that always return Range objects to return
Ref<Range> instead of PassRefPtr<Range>.

One API (rangeFromLocationAndLength) may return nullptr, so its return type
is now RefPtr<Range>.
