Do not propagate <uses-library> deps through static SDK component libs.
If some Java library/app depends on an SDK component library (e.g. stubs
library), then it transitively depends on the SDK library itself
(because the component library has a dependency on its SDK library).
Previously having this transitive dependency resulted in adding the SDK
library to the <uses-library> dependencies of the library/app. However,
this doesn't make sense if the app has a *static* dependency on the
component library. This patch stops adding <uses-library> dependency in
that case.
Bug: 132357300
Test: m nothing
Test: added new Soong test that would previously fail with an error:
invalid build path for <uses-library> "fred"
