[desktop] Data Manager, data import/export (#2700)

This adds a "Data Manager" dialog to the Tools menu. The Data Manager allows for the following operations:
- Open w/ system file manager
- Clear
- Export
- Import

On any of the following directories:
- Save (w/ profile selector)
- UserNAND
- SysNAND
- Mods
- Shaders

TODO for the future:
- "Cleanup" for each directory
- TitleID -> Game name--let users clean data for a specific game if applicable
