Fix Android 16 KB alignment by removing Flipper

[cristhianescobar]

Summary

• disable legacy JNI packaging in the Android app so packaged native libraries are emitted correctly for 16 KB page-size devices
• remove the Flipper and SoLoader debug stack, which was pulling in arm64 native libraries with 4 KB ELF LOAD alignment (libflipper.so, libcrypto.so, libevent*.so, libfbjni.so, and Flipper's libc++_shared.so)
• remove stale Aligned16KB lint baseline entries that still referenced raw Gradle-cache artifacts instead of the packaged APK

Validation

• ./gradlew :android:app-newm:assembleDevelopmentDebug
• ./gradlew :android:app-newm:lintVitalProductionRelease
• inspected the rebuilt app-newm-development-debug.apk and confirmed the Flipper native libraries are no longer packaged
• checked the remaining lib/arm64-v8a/*.so binaries in the debug APK and found no ELF LOAD segment alignment below 0x4000
• zipalign -c -P 16 -v 4 android/app-newm/build/outputs/apk/development/debug/app-newm-development-debug.apk
