COMP: Remove broken .wrap files for incorrectly-wrapped classes

Delete 7 wrapping files that passed wrong template argument counts:
- Regularizer, CurvatureRegularizer, DiffusionRegularizer,
  ElasticRegularizer, GaussianRegularizer: use itk_wrap_image_filter
  with 2 image types but the classes take 1 param (TDisplacementField)
- StopCriterion: takes (TRegistrationFilter, TMRFilter), not images
- MultiResolutionFilter: takes 4 params, wrapping provides 2

These files were already disabled in wrapping/CMakeLists.txt but
the Python package builder may scan the directory and pick them up,
causing compile errors during wheel builds.
