fix #10239 indicate already uploaded gpx tracks

Fix #10239
Indicate which gpx tracks have already been uploaded to OSM. The information is maintained by populating the already existing field lastUploadedTime in the GPX database on a successful upload. A track is already uploaded if lastUploadedTime >= lastModifiedTime.
The additional information is only visible when selecting the upload action in the My Places view.

This UI is questionable and need to be reviewed by the team

I also struggeled with the UI, thus i'm open to other recommendations to depict this information.

Options i experimented with:

1. Single icon without text, e.g. the icon which is used for the action itself. However thereby it seems not clear whether already uploaded tracks or tracks which need to be uploaded are indicated. Maybe a good icon can solve this or one has to use two different icons and mark all tracks.
   Positioning:

   • behind track title
   • right beside track time
   • bigger icon on the right hand side where three dots and switches are shown in other views

2. Icon with text, thus its more clear what is indicated.
   Positioning:

   • behind track title / right beside track time - problem on smaller devices
   • current implementation below other stuff - uploaded tracks and non-uploaded tracks are not of equal height

For all scenarios it seems reasonable to only show the additional information in the upload view.
