This PR adds a new media view written in SwiftUI

Things to be implemented:

• Add zoom in and zoom out to new media screen #2583
• Interchange '+/-' with 'Select' from 'NCMedia+Menu' #2584
• New Media View - Performance optimizations #2619
• New Media View - Loading indicators #2613
• In Media View, show new photos as indicator instead of auto scrolling to top #2612
• New Media View - Additional fixes/features #2672

This closes #2399

In landscape mode isn't full screen :

When select a image the navigation bar isn't normalized :
note. navigationController?.setFileAppreance()

[marinofaggiana]

When scroll the images down quickly the queue of preview is not deleted, the result is that you have to wait a very long time before all previous images are loaded (see old code).

@marinofaggiana What do you think about the performance when zoomed out fully?

IMO the performance is not good, and we can open a separate issue to try and fix it as much as possible by:

• Looking at the profiler and checking what causes low framerate and fixing it

• Replacing normal Image View with NukeUI or Kingfisher for better performance. I already tried briefly using NukeUI, but it needs additional work

  • Caching should be done by NukeUI instead of Realm
  • Some SwiftUI code needs to be rewritten

Yeah maybe doing this would help with performance a bit
