The DLL ships with the games and having the built-in version in system32/syswow64 has unexpected consequences. If the game is launched from a subdirectory, but the DLL is in current working directory, the built-in takes precedence as CWD has lower search priority than system directories (with the default SafeDllSearchMode). By not installing amd_ags_x64.dll in system32/syswow64 the built-in is still picked up correctly from lib/ when necessary. There's an accompanying patch for wine that makes sure wineboot won't install the dll, but since we construct our default_pfx in a special way we also need to make sure that files won't get copied/linked there. To make prefix updates smooth this change also removes any stale amd_ags_x64.dlls that may have been installed by previous version of Proton. CW-Bug-Id: 18804
