Kiyoung Kim 487689eaee Introduce cc_api_library
Introduce cc_api_library, which reflects imported API from other
inner-tree. This cc_api_library module type will later refer from
the other ninja module which generates stub library from the interface
description.

Tested environment :
* original libc definition has been removed temporarily, to ensure that
  imported api stub library is being used from build
* Added new definition of libc as below
 cc_api_library {
  name: "libc",
  arch: {
    x86: {
      src: "libs/x86/libc.so",
    },
    x86_64: {
      src: "libs/x86_64/libc.so",
    },
  },
  header_libs: [
    "libc_headers",
  ],
  export_header_lib_headers: ["libc_headers"],
  min_sdk_version: "9",
  vendor_available: true,
 }

Bug: 236087698
Test: `ALLOW_MISSING_DEPENDENCIES=true m vendorimage` succeeded
