Fix the editor shortcuts for the game menu on Android

[m4gr3d]

A few editor shortcuts were added to the GameView constructor in #103841. That constructor however is not invoked on Android, causing the shortcuts to be missing.
To address that, the shortcuts were moved to the GameViewDebugger constructor, which is invoked on Android.

Fixes the following error logs:
