[GEO] Removing unnecessary orientation enumerators

PR #8978 included 4 unnecessary enumeration values ('cw', 'clockwise', 'ccw', 'counterclockwise'). Since the ShapeBuilder.parse method handles these as strings and maps them to LEFT and RIGHT enumerators, respectively, their enumeration counterpart is unnecessary. This minor change adds 4 static convenience variables (COUNTER_CLOCKWISE, CLOCKWISE, CCW, CW) for purposes of the API and removes the unnecessary values from the Orientation Enum.

closes #9035
But you can replace wherever the boolean is used with equality to the enum value:

`orientation.valueOf()` -> `orientation == Orientation.RIGHT`
