Move nodeIsUserSelectAll() out from PositionAlgorithm template class

Move nodeIsUserSelectAll() out from PositionAlgorithm template class

This patch moves |nodeIsUserSelectAll()| out from |PositionAlgorithm| template
class to "EditingUtilities.cpp" to simplify |PositionAlgorithm| class for
improving code health, since |nodeIsUserSelectAll()| doesn't depend on
|Strategy| template parameter.

BUG=518738
TEST=n/a; no behavior changes
