gmscompat: Make missing play games notification blockable

[FSaurenbach]

Fixes GrapheneOS/os-issue-tracker#7442
tested on latest emulator
if needed i can also try to add the don't show again button to the notification

Some games break when Play Games is missing. To fully address this issue, suppression of the notification needs to be per-app.

No, they are intentionally not suppressible.
