The friendly wrapper for `NetFreeAadJoinInformation()` is pointless.

Actual behavior

The generated friendly wrapper for NetFreeAadJoinInformation() is:

internal static unsafe void NetFreeAadJoinInformation([Optional] winmdroot.NetworkManagement.NetManagement.DSREG_JOIN_INFO? pJoinInfo)
{
    winmdroot.NetworkManagement.NetManagement.DSREG_JOIN_INFO pJoinInfoLocal = pJoinInfo ?? default(winmdroot.NetworkManagement.NetManagement.DSREG_JOIN_INFO);
    PInvoke.NetFreeAadJoinInformation(pJoinInfo.HasValue ? &pJoinInfoLocal : null);
}

Expected behavior

Because this P/Invoke frees pointed to memory, there shouldn't be a friendly wrapper that accepts a dereferenced instance of DSREG_JOIN_INFO.

Repro steps

1. NativeMethods.txt content:

NetFreeAadJoinInformation

2. NativeMethods.json content (if present): N/A

3. Any of your own code that should be shared? N/A

Context

• CsWin32 version: 0.3.264
• Win32Metadata version (if explicitly set by project): N/A
• Target Framework: net472
• LangVersion (if explicitly set by project): N/A

Reproduce the issue with a NativeMethods.txt entry containing NetFreeAadJoinInformation; NativeMethods.json is not needed for the stated repro. Inspect the generated friendly wrapper and the corresponding P/Invoke declaration, then verify that generation keeps the P/Invoke while omitting the pointless dereferenced-struct wrapper.
