Add deprecated cores to mark them as broken for the add-on browser

[garbear]

Description

We tried to delete deprecated cores from the server, but they still show up in the add-on browser because they're probably still hanging out for old version of kodi. So instead, let's reintroduce the cores, then mark them as deprecated in their addon.xml.

Adds the following deprecated cores:

• 4do - https://github.com/kodi-game/game.libretro.4do
• fblpha - https://github.com/kodi-game/game.libretro.fbalpha
• gme - https://github.com/kodi-game/game.libretro.gme
• mupen64plus - https://github.com/kodi-game/game.libretro.mupen64plus
• reicast - https://github.com/kodi-game/game.libretro.reicast
• vice - https://github.com/kodi-game/game.libretro.vice

How has this been tested?

Successful CI run with all 6 cores: https://dev.azure.com/themagnificentmrb/kodi-game-scripting/_build/results?buildId=1422&view=logs&j=b724a4ce-d971-5e6e-9f98-76134d834be3
