Add experimental session replay capturing for Android

[tustanivsky]

This PR adds Android session replay support, leveraging the new SurfaceView capture path introduced in sentry-java 8.41.0 (getsentry/sentry-java#5333) so that Unreal Engine's render surface is included in the captured video (previously SurfaceView regions appeared as transparent/black holes).

Example crash event with session replay captured on Android.

Key changes

• Forward the existing AttachSessionReplay setting through the Android subsystem to the Java bridge.
• When the setting is enabled, configure session replay with sessionSampleRate=1.0 and captureSurfaceViews=true.
• Bundle the new sentry-android-replay AAR via UPL and add kotlin-stdlib-jdk8:1.9.24 to the Android Gradle dependencies
• scripts/build-android.sh and scripts/build-deps.ps1 now also build and copy sentry-android-replay-release.aar.
• Ported the sentry-native-ndk download step from build-android.sh to build-deps.ps1, so -Java is now a complete drop-in replacement for the CI-produced Android artifact (previously it wiped the directory without restoring native-ndk)

Limitations

Currently, frame rate and replay duration aren't configurable since sentry-java keeps these @ApiStatus.Internal with no public setters.
