[BITV]: Replace custom tooltips with native one for files

[JuliaKirschenheuter]

Replace custom tooltips with native one in files:

• app.js
• file-upload.js
• fileactions.js
• filelist.js
• files.js
• mainfileinfodetailview.js
• newfilemenu.js
• operationprogressbar.js
• mainfileinfodetailviewSpec.js

This is a part of nextcloud-libraries/nextcloud-vue#2503
