Support additional optimized resource table flags

**Is your feature request related to a problem? Please describe.**
When building APKs with Gradle, it is possible to set `android.enableResourceOptimizations=true` which will optimize the resource table by collapsing resource names and shortening resource paths.

Reference: https://cs.android.com/android-studio/platform/tools/base/+/mirror-goog-studio-main:build-system/gradle-core/src/main/java/com/android/build/gradle/internal/tasks/OptimizeResourcesTask.kt;l=165-169?q=OPTIMIZED_PROCESSED_RES

This is currently not supported in App Bundles as called out in the following issue: https://partnerissuetracker.corp.google.com/issues/217593048

**Describe the solution you'd like**
Add new fields in `ResourceOptimizations` in the bundle config that allow enabling collapse resource names and shorten resource paths.

Internally, enabling these would pass the following flags into the aapt2 command: `--collapse-resource-names` and `--shorten-resource-paths` into `aapt2`
