Add .internal modules to IDEInfo.deps of top-level java_sdk_library

libraries and apps can depend on the top-level java_sdk_library like
such
```
java_library {
  name: "mylib",
  libs: ["somesdklib"],
}
```
and soong will automatically resolve mylib's classpath to either the
stub or impl library based on the api container these libraries are in.

Since the top-level java_sdk_library has no compilation actions, code
completion of `mylib` is not feasible today via
`module_bp_java_deps.json`. This CL adds support for this code
completion by registering the .impl (or public stubs) as a transtive
dependency of `mylib`.

The implication of this change is that implementation symbols of the sdk
library will be surfaced during code-completion of mylib, even when
mylib is in a different container. Long term, this should go away when
all the library dependencies are made explicit in Android.bp files.

Test: go build ./java
Test: verified that symbols of android.car.builtin (a java_sdk_library)
can be resolved with the repro instructions in b/356572093#comment5
