Signature is incorrect for many callbacks

Microsoft.Windows.WDK.Win32Metadata 0.13.25-experimental contains these definitions:

namespace Windows.Wdk.System.SystemServices;

[StructLayout(LayoutKind.Auto, CharSet = CharSet.Auto)]
[UnmanagedFunctionPointer(CallingConvention.Winapi)]
public unsafe delegate NTSTATUS EX_CALLBACK_FUNCTION([In] void* CallbackContext, [Optional][In] void* Argument1, [Optional][In] void* Argument2);

[StructLayout(LayoutKind.Auto, CharSet = CharSet.Auto)]
[UnmanagedFunctionPointer(CallingConvention.Winapi)]
public delegate NTSTATUS PEX_CALLBACK_FUNCTION();

where PEX_CALLBACK_FUNCTION has a bad signature and EX_CALLBACK_FUNCTION is unused anywhere. PEX_CALLBACK_FUNCTION should be remapped to EX_CALLBACK_FUNCTION.

This pattern is repeated for a number of callback types. Many of the types in emptyDelegatesAllowList.rsp have this issue and should be removed from the allowlist.

This seems like the same issue as https://github.com/microsoft/wdkmetadata/issues/47.

Start by inspecting emptyDelegatesAllowList.rsp and the generated callback definitions shown in the issue. Compare the allowlisted types with the EX_CALLBACK_FUNCTION and PEX_CALLBACK_FUNCTION pattern, using issue #47 for context. Done means affected allowlist entries are removed and callback signatures are remapped consistently.
