C++: Fix crash reported in #7721

objc_libraries used to always take the static libraries of C++ dependencies even if dynamic libraries were available. This is because support for dynamic linking of C++ dependencies hasn't been added to objective-C rules yet.

With https://github.com/bazelbuild/bazel/commit/3e727b19ee5b44162f5548aa01599256f3602715#diff-033df3f3a834149658486b8a5754baefL438, we started propagating both static libraries and dynamic libraries in the new implementation of LibraryToLink. Since cc_test by default will always try to link dynamically, the behavior changed and if we had the dependency chain cc_test -> objc_library -> cc_library; the cc_test would start using the .so file from the cc_library, whereas before it used the .a file. Linking the .so file gives an error since as mentioned, support for this hasn't been added to Objective-C.

The fix has been to nullify the dynamic library fields of LibraryToLink as long as a static library was present. This makes the behavior the same as before.
