Rework for Android builds/workflows

[MatusGuy]

This pull request scraps the old android builds that used ndk-build/makefiles for a better and more compatible CMake solution

commits are pretty unorganized

marked as draft because some stuff is yet to be implemented:

• [x] downloading addons
• [x] auto locale
• [x] keyboard
• [ ] tweak funky button hitboxes (optional)
• [ ] opengl es (optional)
• [x] workflow builds but generates unplayable apk, fix that
• [x] some workflows stopped working because of this one, fix that
• [x] fix weird aspect ratios i guess? (tempfix)
• [x] split workflow into architectures (optional)
• [ ] sync

android workflow builds successfully but generates unplayable APK

It takes a lot of patience to get this working

[MatusGuy]

[MatusGuy]

[MatusGuy]

[MatusGuy]

[MatusGuy]

I'm starting to get a biiit impatient... Should we ditch OpenGL ES support and tweaking button hitboxes?

[MatusGuy]

Arrrg.

[MatusGuy]

It just booted. Great! Why is it stretched???? I didn't touch it!!!!

[MatusGuy]

Right now fixing errors with other workflows. Who turned on -Werror for some workflows???

[MatusGuy]

Holy crap. Most of them are fixed. yippie

[MatusGuy]

Now what's left is Windows. Grr...

[MatusGuy]

ok. looks like split archs are working. this is great. btw i might've messed up android workflows and now they end up at https://github.com/MatusGuy/supertux/actions/workflows/android.yml because they're disabled in upstream

[MatusGuy]

caching works i guess?

[MatusGuy]

Depends on #2621
