[aapt2] Add --non-updatable-system flag
This adds `updatableSystem="false"` to the root <manifest> tag if no
versionCode is specified (either explicitly or through --version-code).
This attribute makes the APK not updatable (see b/266131956).
Bug: 328302305
Test: atest aapt2_tests
Test: Manually ran `aapt2 link --non-updatable-system` and verified the
resulting APK.
