cc_shared_library ignores objc_library transitive dependencies

[keith]

Description of the bug:

If you have a cc_shared_library with a direct dependency on an objc_library it fails to build with this error:

Traceback (most recent call last):
        File "/virtual_builtins_bzl/common/cc/cc_shared_library.bzl", line 666, column 114, in _cc_shared_library_impl
        File "/virtual_builtins_bzl/common/cc/cc_shared_library.bzl", line 382, column 48, in _filter_inputs
Error: <target //:bar> (rule 'objc_library') doesn't contain declared provider 'GraphNodeInfo'
ERROR: /private/tmp/objc_library_cc_shared_library/BUILD:11:18: Analysis of target '//:baz' failed

If it has a transitive dependency instead, it is ignored and the symbols from it are not linked in.

You can work around this now with this:

    additional_linker_inputs = [
        ":lib",
    ],
    user_link_flags = [
        "$(location :lib)",
    ],

cc_shared_library wasn't designed with objc_library rules in mind so I'm surprised it even works with that small workaround. Looking quickly at the objc_library rule definition it doesn't announce that it provides CcInfo with provides = . If all the information that you need is in CcInfo and the rule starts announcing that it provides it, then it should work. Apart from that the cc_shared_library rule doesn't currently make any special considerations for objc_library.
