ci(android): fix split build, produce universal APK in the same Gradle run
Build Android APK / Build Release APKs (push) Successful in 14m40s
Details

Browse Source 
The previous commit made `assembleRelease` depend on AGP's
`packageReleaseUniversalApk`. That task derives the universal APK from an
App Bundle, which pulls `buildReleasePreBundle` into the graph - and AGP
refuses to build a bundle while ABI splits are enabled
("Multiple shrunk-resources files found ... Please disable building
multiple APKs when building an Android app bundle", run 52).

Instead only flip `splits.abi.universalApk` back on when Flutter passes
`-Psplit-per-abi=true`: the Flutter Gradle plugin enables the splits and
copies every output - including the universal one, as app-release.apk -
to build/app/outputs/flutter-apk/. Plain builds (`flutter run`) keep the
plugin's abiFilters path, which AGP does not allow together with splits.

Workflow: one `flutter build apk --release --split-per-abi` call, copy the
four well-known output names (a missing one fails the step), job timeout
60 min (a green run takes ~17), drop the unneeded platform pre-install and
add a per-ref concurrency group - runs 50/51 ran in parallel on the single
ARM64 runner and both died at the same instant.

Verified locally with Flutter 3.47.4: split build yields all four APKs
(universal 62 MB, per-ABI 20-24 MB) in one Gradle run; plain release
build still produces app-release.apk.
