UI: Disable default path setting when file path is selected
Description
Add path value check (whether empty) when open path/file selecting dialog, to achive only using default_path when path value is empty.
Motivation and Context
Fixes #6777
In most cases, the default_path setting should only work when the path is empty, but in current situation, it looks not work well when the path is changed to other directory or is set from empty. Beacuse the properties view (default_path argument) is not updated after changing the path.
