Handle deprecated transformer classes

[DN6]

What does this PR do?

transformers main has deprecated CLIPFeatureExtractor. Since a lot of pipeline configs have this object in the model index, we run into errors such as #12492 when loading those pipelines with the latest transformers.

This PR:
Introduces a remap check for transformer class names and updates to the correct class based on the installed transformer version.
