Enable R8 full mode by default for apps
This provides significant size savings over the default compatibility
mode, roughly ~20MB in aggregate for a recent Pixel build. Targets can opt out using `proguard_compatibility = true`.
Future work will enable for all targets, not just apps, but this
incremental change yields the most benefit.
