Remove constructor options from TransformXY methods

[peterstace]

Description

The TransformXY methods transforms the coordinates of geometries in arbitrary ways via a user-supplied mapping. It should be obvious that this potentially could cause invalid results. For example, the mapping could trivially map every coordinate pair of a polygon to the same point. In practice, transformations are either affine (translation, rotation, scaling), or, at the very least, topologically preserving (e.g. WGS84 to a Mercator or Conic projection).

This change removes the choice to validate or not in TransformXY methods, always omitting a validation step. Users can still validate manually via the Validate method if they wish to.

Check List

Have you:

• Added unit tests? No, however existing tests have been updated.

• Add cmprefimpl tests? (if appropriate?) N/A.

• Updated release notes? (if appropriate?) No, release notes will be updated when all ctor option related changes have been made.
