Upgrade source-download SDL to 2.28.5

Looks like this is all that was needed for Android to build, let's see how other platforms will react

WARNING: I play tested the build on my Google Pixel 2 with Android 11, but I would recommend to play test the CI build on couple more devices before this is merged

P.S. I don't know why Android Studio had to change the whole file when I committed 2 lines, so look at SDLActivity.java changes with "Hide whitespace" ON

error: static assertion failed due to requirement '27 == 28': SDL_MINOR_VERSION == SDL_BUILD_MINOR_VERSION
error: static assertion failed due to requirement '0 == 5': SDL_PATCHLEVEL == SDL_BUILD_MICRO_VERSION

The errors are due to cached SDL version in the runners
Can we rerun the jobs with busted cache? Figured it out, you need to update cache number in workflow .yml files

Rather then patching the SDL Java files could you please copy them from the same release of SDL as is used on the C side of things: https://github.com/libsdl-org/SDL/tree/release-2.28.5/android-project
Else we are left with a hybrid where the Java portion is using an older version then the C part, this is what is causing the issue currently (the C portion was updated, but the Java part was not).

Sure, no problem
The main changes are in SDLActivity.java (changes to InputDevice.SOURCE_MOUSE) and HIDDeviceManager.java (adding new controller device IDs) the rest are just comments for magic numbers
