Generated app id with hashed input data

[brad-richardson]

Description

Generate stable app id based on name and image data hash. This allows us to stop persisting ids altogether and prevents us filling up moonlight's cache if ids are changing often.

To test:

• Changing image data without changing path
• Removing image path
• Duplicate apps with same name + image path
• No apps

Issues Fixed or Closed

• Should fix bug reported on Moonlight discord
