wasapi: Don't redefine GUIDs when building under newer MinGW

Browse source 
Latest MSYS2 MinGW provides these now, so we don't need to define them
if they're already present in the header.

The AudioClient3 GUID requires the Windows 10 SDK, so it's only
available in the latest MinGW, and the MinGW in Cerbero is too old.
