DOC: Clean up itk::ConformalFlatteningMeshFilter Doxygen documentation

Clean up method Doxygen documentation for
`itk::ConformalFlatteningMeshFilter`:
- Consolidate documentation so that methods are documented in the header
  files.
- Remove empty method documentation blocks from implementation file.

Take advantage of the commit to make the modified method documentation
blocks have a consistent line length.

Follow-up to d58bf56.
