Bump NetworkStack to SDK 31
- Set build SDK to module_31 instead of system_30 in release
target
- Set target SDK to 31 in release target instead of 30
- Update version codes as per convention
- Move "current" shim library to api31 shims
- Add new "current" shim library for next development SDK
Ignore-AOSP-First: SDK 31 does not exist in AOSP. Will be partially
cherry-picked.
