ENH: Use itkOverrideGetNameOfClassMacro as per ITK PR 4373

See related ITK PRs:

InsightSoftwareConsortium/ITK#4378

We should probably wait until ITK 5.4 final is tagged, before merging this.

As-is, this breaks the python builds with GitHub action for remote modules:

I assume we would get a better sense of what's going on after the ITK commit hashes are updated in the CI config file:
https://github.com/InsightSoftwareConsortium/ITKModuleTemplate/blob/main/.github/workflows/build-test-package.yml#L6-L8

So:

We should probably wait until ITK 5.4 final is tagged, before merging this.

Looks the way forward to me.
