Allow customizing user:// path (folder in OS::get_data_path())

Browse Source 
This allows to specify any valid folder name (including with subfolders) to use
as user:// on all platforms. The folder is constrained to the platform-specific
OS::get_data_path() (typically what `XDG_DATA_HOME` resolves to).

Fixes #13236.
