Link explicitly to private transitive dependencies on stub libraries
We represent stub libraries, e.g., for CUDA, using imported `SHARED`
library targets with only `IMPORTED_IMPLIB`, and no `IMPORTED_LOCATION`,
to indicate that the stub file is meant only for linkers and not dynamic
loaders. See commit 7351d590ee (cmTarget: Add a way to represent
imported shared library stubs, 2023-07-17, v3.28.0-rc1~344^2) and commit
fc6508921c (cmComputeLinkInformation: Restore soname lookup for
non-imported targets, 2023-12-05, v3.28.0~4^2).
If a shared library is linked to a stub, it has a `NEEDED` field
populated with the `SONAME` found in the stub. When a dependent target
links to such a shared library, some linkers want to find a library file
on disk and load it to see what symbols it provides. This is necessary
for linkers that enforce `--no-allow-shlib-undefined`. On hosts with
only the stub library installed, e.g., with only the CUDA toolkit
development package, the real runtime library corresponding to the
stub's `SONAME` may not even exist, so no `-rpath-link` flag can help
linkers find it. Pass the stub library to linkers explicitly so they
can find it without searching.
