Add SDK member support for cc_object.

Test: m nothing
Test: Add
    sdk {
        name: "runtime-module-sdk",
        native_shared_libs: [
            "libc",
            "libdl",
            "libm",
            "ld-android",
        ],
        native_objects: [
            "crtbegin_dynamic",
            "crtbegin_static",
            "crtend_android",
        ],
    }
  to bionic/apex/Android.bp. Then:
    build/soong/scripts/build-aml-prebuilts.sh runtime-module-sdk
  Take the generated runtime-module-sdk-current.zip and unzip into a
  master-art tree without bionic/, edit the generated Android.bp to
  extend cc_prebuilt_* modules with:
    nocrt: true,
    stl: "none",
    system_shared_libs: [],
    apex_available: ["//apex_available:anyapex"],
    recovery_available: true,
    vendor_available: true,
    ramdisk_available: true,
  Then "m com.android.art.debug". This passes Soong but fails in the
  build step because more members are required.
