fix: stop no-build pack writing project .aar files that dependent projects race on

With --no-build, pack reaches _CreateAar through ResolveReferences after the
native library inputs have been extracted, so it writes <Project>.aar mid-pack.
Dependent Android projects packed in parallel hash that file in
ResolveLibraryProjectImports and fail with XARLP7024 on Linux.

Closes #5092
