Support prebuilt libraries in prebuilt_apis.go 

When the sdk_version or LOCAL_SDK_VERSION is not current or
TARGET_BUILD_APPS is not null, module will use the prebuilt
libraries. For this, prebuilt libraries are supported in
prebuilt_api.go

Bug:77577799
Test: make -j
Test: make -j TARGET_BUILD_APPS='camera2_stubs_test'
      and check intermediates files
