Support additional optimized resource table flags

[benjaminRomano]

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
