Add golden test for ApfGenerator on IPv4 WiFi network

Automatically generated via:
  //hardware/google/apf/apf2java/apf2java.sh
(which is an APF disassembly to java test bash/sed script).

The apf byte code itself was extracted from a IPv4-only wifi network
connected device running:
  google/oriole/oriole:14/UQ1A.231205.001/10959544:userdebug/dev-keys
and converted from hex via the apf_disassembler.

See: aosp/2922474

Bug: 320199061
Test: TH
Change-Id: Iab8c42c2fce34120df862028e16cc9642d742a22
