Prune ComputeVisibleSelectionInDOMTreeDeprecated from GranularityStra…

…tegy

This patch prunes the deprecated function GranularityStrategy::UpdateExtent
(both overrides) and its caller FrameSelection::MoveRangeSelectionExtent.
The change is safe because these functions are reachable only from
WebLocalFrameImpl::MoveRangeSelectionExtent, where layout has been updated.

BUG=698633
TEST=n/a; no behavioral changes.
