Toggleable public/private upload

Rerolled #38 for 9.5.x

small compatibility fix for Drupal 10 undefined call to file_move

fix stupid issue with previous patch where i passed the plain file object to move instead of calling getFileUri on it.

The #45 patch is a small step forward but some odd things:

When creating a new Media entity with this patch enabled:

First add file, then select private storage.
-Upload a file
-Select Private storage
-Save entity
-Edit media entity again.
-Notice it has been stored as a public file.

First select storage, then upload a file.
-Set storage to private.
-Upload a file
-Notice that private has been reset to public, set to private again
-Save entity
-Edit media entity again.
-Notice is has the correct setting, private storage.

Now when you want to change the file from private to public it is not possible anymore. It will always be private.

Used correct service this time.

Try to fix patch #47.

Issue summary could use some updating.

Updated the patch to be compatible with the latest 10.5.x release.

Main differences:
1. Updated imports in FileWidget.php to match Drupal 10.5.x structure
2. Fixed import ordering to be compatible with current codebase

core/modules/file/src/Plugin/Field/FieldWidget/FileWidget.php:
- Added missing import for StreamWrapperInterface (line 14)
- Added missing import for FileInterface (line 19)
- Adjusted import ordering to match Drupal 10.5.x conventions
- Added use statement for Drupal\Core\Url which was missing in patch #49

Technical details:
------------------
The original patch #49 failed to apply to Drupal 10.5.x because:
1. The import structure in FileWidget.php changed between versions
2. Additional imports (like Drupal\Core\Url) were added to 10.5.x
3. The patch context didn't match the current file structure

These changes make the patch compatible with Drupal 10.5.x while
maintaining all the original functionality for the uri_scheme_field feature.

All other functionality remains identical to patch #49.
