Move LLNDK related logic to llndk_library
Currently VNDK contains some logic for LLNDK libraries as they are
treated in a similar way with VNDK. However, those logics should stay from
VNDK deprecation. To keep the logic, this change moves LLNDK related
logic into llndk_library.
Bug: 330100430
Test: Soong tests passed
Test: llndk.libraries.txt did not change from CF build
