Merge "Selection API: type attribute should return 'Range' for range-selection in text controls." to M59

This fixes a regression since Google Chrome 58. New behavior is compatible with
WebKit and Edge. Firefox doesn't have 'type' attribute.

Implementation:
SelectionTemplate<T>::IsCaret() and IsRange() should take care of granularity.
