feat: Support for the Android 12 new splash screen system

[M123-dev]

Now we support Android 12 splash screens

@M123-dev Please remind me: is there a good reason why we switch to Android 12 (aka 31)? In my apps a user reported me another bug due to Android 12.

@monsieurtanuki when we added permission_handler for asking for camera permission I checked if we fully switched to AndroidX (since the package needs it) and then upgraded to target version to 31, but android 11 will be probably fine as well. Is android 12 really that buggy

[monsieurtanuki]

@M123-dev If the package needs it and if we need the package, that's solved: go for 31.
But so far 31 is the first Android version upgrade that brought trouble in my Android/java apps, like crash at init time. I started around 21 - that means 9 harmless Android version upgrades before 31.

It's not really bugs, it's about evolutions like: "if this flag is not set, from 31 we crash", or "the Toasts size is less than 16 characters from now on" (instead of possibly several lines).

@monsieurtanuki, I am going to try to downgrade the target to 30 for #1038

AFAICR the country selector library only worked with Android 31 ... (I think)
