[Library] Disable Play button while launching game

[arielj]

This is a workaround for #2115

There are two changes:

• added a new isLaunching state in the card component to be able to disable the button while we wait for the game to start (we should detect that it's doing a save sync and show that in the UI)
• only do sync saves if the user enables the option instead

---

Use the following Checklist if you have changed something on the Backend or Frontend:

• Tested the feature and it's working on a current and clean install.
• Tested the main App features and they are still working on a current and clean install. (Login, Install, Play, Uninstall, Move games, etc.)
• Created / Updated Tests (If necessary)
• Created / Updated documentation (If necessary)
