build(android): generate AAR dependencies from sdl3Aars list

[dwvwvvwvwb]

Summary

Build "Dynamically include SDL AARs from sdl3Aars list"

Purpose of change

The dependencies block currently hardcodes exact filenames of SDL AARs (e.g. SDL3-3.4.10.aar). This forces manual updates every time we upgrade SDL versions and creates inconsistency with the sdl3Aars list used for downloading.
This change makes the dependency list automatically reflect the versions defined in sdl3Aars, improving maintainability without altering any functionality.

Describe the solution

Replace the explicit implementation files(...) list with a loop over sdl3Aars in the dependencies block. Each entry generates implementation files("libs/${entry.name}-${entry.version}.aar").
No version numbers are changed – the existing sdl3Aars remains untouched.

Describe alternatives you've considered

• Using fileTree(dir: 'libs', include: ['*.aar']) – simpler but less explicit; could accidentally include unrelated AARs. Looping over sdl3Aars is safer because it only includes what we explicitly want.

Testing

• Ran ./gradlew clean to ensure a fresh state.
• Executed ./gradlew assembleRelease – build completed successfully.
• No runtime regressions are expected because the resulting classpath is identical (same AAR files, same versions).

Additional context

None – this is a pure build script refactor with zero impact on the game's code or behavior.
