Templatize expandSelectionToRespectUserSelectAll in SelectionController

Templatize expandSelectionToRespectUserSelectAll in SelectionController

This patch introduces a template funciton |expandSelectionToRespectUserSelectAllAlgorithm<Strategy>|
for a preparation of makeing static function |expandSelectionToRespectUserSelectAll()|
to work with both DOM tree and composed tree.

Following patch will make |expandSelectionToRespectUserSelectAll()| to check
runtime flag |SelectionForWebComponents| and work for either positions in DOM
tree or positions in composed tree.


This patch is result of collaboration work with hajimehoshi@chromium.org
for selection of web components. After this patch, we are going to
implement another strategies for the composed tree. We've already
prepared that at http://crrev.com/1106433002.

BUG=275851
TEST=n/a; No behavior changes.
