feat: add config for temp path and temp path cleanup on launch (lllyasviel#1992)

* Added options to set the Gradio cache path and  clear cache on launch.

* Renamed cache to temp

* clear temp

* feat: do not delete temp folder but only clean content

also use fallback to system temp dir
see https://github.com/gradio-app/gradio/blob/6683ab2589f9d8658e1f51acc1b7526edce988d3/gradio/utils.py#L1151

* refactor: code cleanup

* feat: unify arg --temp-path and new temp_path config value

* feat: change default temp dir from gradio to fooocus

* refactor: move temp path method definition and configs

* feat: rename get_temp_path to init_temp_path
