Removes constants from `CATextLayer` (only for XAMCORE_4_0) and creates
two smart enums `CATextLayerTruncationMode` and `CATextLayerAlignmentMode`.
Also this introduces two new strong properties into CATextLayer class,
`TextTruncationMode` and `TextAlignmentMode` that takes the new enums
respectively, these new properties are meant to replace their
string counterparts `TruncationMode` and `AlignmentMode`.
