This removes the !_WIN64 guards for X3DAudio's and XAPOFX's DLL_WINE_PREATTACH cases for Proton.

The main reason we prefer the builtins for 64-bit is because XAudio2 has some strange behavior on Win64 for reasons unknown. However, that only applies to XAudio2_*.dll; the other XAudio2 libraries should be perfectly safe to use. We still use FACT for XACT3 support since FACT works best with FAudio, but we can get some pretty good accuracy improvements from using Microsoft's X3DAudio (accuracy in F3DAudio still isn't great) and get all the proper effects from the official XAPOFX library (which we don't have implemented at all right now).

Interesting. Can you list some games this helps?

Bethesda games (Skyrim, FO4), UE3/UE4 games (MOTHERGUNSHIP, A Hat in Time, KF2, Soul Calibur 6), Rebellion games (Strange Brigade, Sniper Elite), id Tech 5+ games (RAGE, WolfTNO), Warframe, Hellblade, basically anything that's not using XAudio2 via Wwise.
