[iOS][libFuzzer] Extend visibility rule for some targets

iOS fuzzer_test target builds extra targets than the fuzzer_test itself.
So fuzzer_test deps had to expose visibility to multiple targets. This
change creates an intermediate "{fuzzer}_deps" target for fuzzers, so
the libraries could just expose visibility to this target.
