Add generate_apk=yes to generate an APK after building

[Calinou]

This is useful to speed up iteration when working on the engine (or editor). If you need multiple architectures in the APK, specify generate_apk=yes when building the last architecture you're interested in only.

This can be combined with a script that calls adb to deploy the APK on a device (coupled with Godot's --export-* for projects) to further speed up iteration.

Gradle output is set to --quiet, which means it only leaves persistent messages on errors (progress is visible inline while building):

scons: Reading SConscript files ...
Checking for Android NDK...
Building for platform "android", architecture "arm64", target "template_release".
Checking for C header file mntent.h... (cached) yes
scons: done reading SConscript files.
scons: Building targets ...
Linking Shared Library bin/libgodot.android.template_release.arm64.so ...
progress_finish(["progress_finish"], [])
generate_apk(["platform/android/generate_apk"], [])
scons: done building targets.

Looks good!

Looks good to me. Added a suggestion for further improvements.

Done. Note that using generate_apk=yes with Android editor also generates an .aab file alongside in bin/android_editor_builds. Should I rename the option accordingly?

❯ ll -B bin/android_editor_builds

I think it's fine to use "apk" as a shorthand for Android app package which can be either apk or aab. Might be worth mentioning AAB in the description of the option.

Done 🙂

Needs running black -l120 or shortening the description to keep it on one line.
