Cherry-pick Ravenwood "core" code
- Copied f/b/r and f/b/t/h
- Ported files under f/b/core, only what needed to for run-ravenwood-tests.sh to pass
- Local changes because of missing resoucres support
- Added @DisabledOnRavenwood(reason="AOSP is missing resources support") to tests under f/b/r that depends on resources
bivalentinst and servicestest
- Added try-catch around ResourcesManager.setInstance()
Flag: EXEMPT host test change only
Bug: 292141694
Test: $ANDROID_BUILD_TOP/frameworks/base/ravenwood/scripts/run-ravenwood-tests.sh
Merged-in: I8a9b8374be3ae052ba4f152eb43af20d0871597f
