Distribute Magisk directly with Magisk Manager APK. The APK will
contain all required binaries and scripts for installation and
uninstallation. App versions will now align with Magisk releases.
Extra effort is spent to make the APK itself also a flashable zip that
can be used in custom recoveries, so those still prefer to install
Magisk with recoveries will not be affected with this change.
As a bonus, this makes the whole installation and uninstallation
process 100% offline. The existing Magisk Manager was not really
functional without an Internet connection, as the installation process
was highly tied to zips hosted on the server.
An additional bonus: since all binaries are now shipped as "native
libraries" of the APK, we can finally bump the target SDK version
higher than 28. The target SDK version was stuck at 28 for a long time
because newer SELinux restricts running executables from internal
storage. More details can be found here: https://github.com/termux/termux-app/issues/1072
The target SDK bump will be addressed in a future commit.

The FlashActivity has been removed and all of it's functionality has been transferred to the FlashFragment.
The FlashFragment needs to be however launched in a different way than the activity using the MainActivity's stub and so seemingly massive changes had to be made.
Notably the RemoteFileService didn't seem to be calling Service.startForeground(), which has been crashing the application due to the system requirements, so that's been fixed.
Converted App class and Main activity to Kotlin. With that refactored fields within App class to allow lazy initialization
BEWARE: at this point the navigation is very much broken, won't let you anywhere beyond home screen
