Update static prop source method names to reflect their stability

This affects both the sdc and js ComponentSource plugins, through GeneratedFieldExplicitInputUxComponentSourceBase.

massageFormValuesTemporaryRemoveThisExclamationExclamationExclamation() has been dead for a very long time.

I think this is less urgent.

Agree, but tagging as Novice because its a good toe dipper

Just to confirm, can I rename formTemporaryRemoveThisExclamationExclamationExclamation() to buildPropFormElement()?
Also, since massageFormValuesTemporaryRemoveThisExclamationExclamationExclamation() is marked as dead, should I safely remove it?
Please let me know before I proceed. Thanks!
