Crash when returning a IntPtr when dynamically invoke .NET APIs

Hi!

When I try to invoke dynamically an API which returns an IntPtr (e.g. GetMainProgramHandle()) the process crashes:

C:\Users\xc3ll>node
Welcome to Node.js v16.15.1.
Type ".help" for more information.
> const test = require('node-api-dotnet');
> handle = test.System.Runtime.InteropServices.NativeLibrary.GetMainProgramHandle()

I tested it with other functions and the result is the same.

Start at src/NodeApi/JSValue.cs:609 and reproduce the failure with NativeLibrary.GetMainProgramHandle() from the shown Node.js REPL example. Compare the stack trace with other IntPtr-returning APIs; done means these dynamic invocations no longer crash and return their results successfully.
