[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
I don't think this needs the string/boolean. They can be regular enum values.  And the constants can be inside the enum, so that they can be used as if they were additional values.
