STYLE: CoordRepType -> CoordinateType code readability

For the sake of code readability, a new 'CoordinateType' alias is added for
each nested 'CoordRepType' alias. The old 'CoordRepType' aliases will still be
available with ITK 6.0, but it is recommended to use 'CoordinateType' instead.
The 'CoordRepType' aliases will be removed when 'ITK_FUTURE_LEGACY_REMOVE' is
enabled. Similarly, 'InputCoordinateType', 'OutputCoordinateType', and
'ImagePointCoordinateType' replace 'InputCoordRepType', 'OutputCoordRepType',
and 'ImagePointCoordRepType', respectively.
