shizuku installer automatic temporary fallback

Some apps require to be installed with shizuku in order to be flagged as "installed via microg companion" so they dont complain about missing play store and so on.

I turn on shizuku explicitly for when I install such apps, but for the rest I dont.

The problem is I have to either set aurora store to session installer manually or turn on shizuku so apps will install even when I dont require them to be installed with shizuku/flagged as installed with microg companion.

My suggestion is that aurora store automatically temporarily falls back to session installer if shizuku isnt turned on.

To avoid confusion there could be an optional toast message or prompt that explains/aks the user to fall back to sessions installer since shizuku isnt turned on.
