X3DAudio APIs missing

[morganbr]

The following functions and structs from X3Daudio.h (https://learn.microsoft.com/en-us/windows/win32/api/x3daudio/) are missing. I'm working on a gaming-focused projection where these would be helpful.

Functions:
X3DAudioInitialize
X3DAudioCalculate

Structs:
X3DAUDIO_CONE
X3DAUDIO_DISTANCE_CURVE
X3DAUDIO_DISTANCE_CURVE_POINT
X3DAUDIO_DSP_SETTINGS
X3DAUDIO_EMITTER
X3DAUDIO_LISTENER

Will investigate; metadata is set up to scan X3DAudio but it's missing for some reason. (It also points to XAudio2_8.dll and not XAudio2_9.dll per the import libs, which will also need to be corrected.)
