Upstream commit: https://webrtc.googlesource.com/src/+/b65c6012cf0512e4713fe4c9c834cade2e08e631
       Fix gn gen with rtc_include_internal_audio_device=false

       Before the change the following command were failing:
       ```
       gn gen ../out/Temp --args='target_os="ios"
       is_debug=true
       target_environment="device"
       target_cpu="arm64"
       ios_deployment_target="14.0"
       ios_enable_code_signing=false
       is_component_build=false
       rtc_include_tests=false
       rtc_include_internal_audio_device=false'

       ERROR Unresolved dependencies.
       //:webrtc(//build/toolchain/ios:ios_clang_arm64)
         needs //api/audio:create_audio_device_module(//build/toolchain/ios:ios_clang_arm64)
       ```
