Broken code generated due to hardcoded "PInvoke" classname

[icelandcoherence]

When setting a custom classname (instead of PInvoke), the generated file Windows.Win32.ICCloseSafeHandle.g.cs contains the line

protected override bool ReleaseHandle() => SomeClass.ICClose((winmdroot.Media.Multimedia.HIC)this.handle) == (global::Windows.Win32.Foundation.LRESULT)PInvoke.ICERR_OK;

This uses PInvoke instead of the classname set in NativeMethods.json, which results in the compilation error The name 'PInvoke' does not exist in the current context. It also uses a hardcoded global::Windows.Win32 which I assume should be winmdroot, although this does not error as those are defined to be the same.

Repro steps

1. NativeMethods.txt content:

Windows.Win32.Media.Multimedia

2. NativeMethods.json content:

{
	"$schema": "https://aka.ms/CsWin32.schema.json",
	"className": "SomeClass",
}

Context
