Deprecate "Type" and support more devices for save_on_cpu (#103245)
Fixes #ISSUE_NUMBER
1、the class named "Type" has not been used anymore in anywhere, so I add warning message to remove it in the future.
2、add a arg(default is "cuda") for save_on_cpu so that it can support more device type (like privateuse1)
