Add fix for ANONYMOUS;CODE

This game has been officially reported for lock-ups during playthrough due to audio bugs, and this patch attempts to workaround them by installing xact and disabling esync/fsync. Installing xact and disabling esync/fsync should make the game playable, preventing the need for users to manually download the XAudio2_9.dll as well as setting environment variables as suggested on ProtonDB. In addition, audio for in-game videos are fixed through the GST_PLUGIN_FEATURE_RANK environment variable.

Related to GloriousEggroll@ce019ae GloriousEggroll@e5209e1 GloriousEggroll@fe430fc because it uses the same engine and exhibits the same lock-up symptoms.
