Install transitive deps of jni libs, but not the jni libs themselves

Consider this case:

app --(jni_libs)--> libfoo --(shared_libs)--> libprivate

Only libfoo is embedded into the app. libprivate is not embedded because
libprivate is very likely to be depended on by other components in the
platform, in which case it will anyway be installed to /system/lib.
Embedding libprivate into the app will increase the storage usage as a
whole. Furthermore, if libprivate is not a shared lib but a config file
(of type prebuilt_etc), it can't be embedded and therefore must be
installed outside of the app.

However, a problem occurs when libprivate is not depended on by anyone
else. Then libprivate is not installed to the system partition, causing
an error at runtime.

This CL fixes that by making the jni_libs dependency to implement the
new SKipToTransitiveDepsTag interface. Now, jni_libs themselves are not
installed, but their transitive deps are depended on by the app
containing the jni libs.

Bug: 330276359
Test: m NfcNci and check if libnfc-nci.config is installed.
Test: m CarService and check android.hardware.automotive.evs-V2-ndk.so
is installed as well.
Test: go test ./... under soong/java
