Update ImportSharedLibTask to use AGP 9 APIs

The Project#exec() method is removed in AGP 9. The recommended migration is to define a separate task class that injects ExecOperations to do the execution.

This CL also removes the unnecessary `package` declarations from AndroidManifest, which is ignored as of Gradle 8+.
