Restore CloudLibrary save functionality, revise convert to AMF behavior

- Fixes #111237022 - Unable to save any changes to CloudLibrary items
 - Add useIncrementedNameDuringTypeChange to PrintItemWrapper to control naming behavior
 - Pass useIncrementedName value though from provider factory all the way to PrintItemWrapper
 - Prevent duplicate calls to GetPrintItemWrapperAsync within the same callstack i.e. pass instance through
 - Only rename files when switching to AMF and use different logic for different provider types
 - Add path helper methods to PrintItemWrapper for clarity and conciseness in callers
