clarify different methods

These method names were too similar to existing methods in PureLayout, which
have slightly different behavior.

ows_autoPinToSuperviewEdges uses left/right, whereas PureLayouts uses
leading/trailing

ows_autoPinToSuperviewMargins uses our own constraint adding logic, which
behaves differently in some cases.
