When attempting to use Marshal.GetDelegateForFunctionPointer with the IntPtr returned from "GetProcAddress" (kernal32) when the scripting runtime is set to .NET 4.x Equivalent, the incorrect number of parameters is returned from the delegate's MethodInfo and an exception is raised when calling Delegate.DynamicInvoke when using the correct number of parameters.

To reproduce:

1. Download attached project “DynamicInvoke.zip" and open in Unity
2. Set Scripting Runtime Version to .NET 4.x Equivalent
3. Click on the Custom menu item "Editor/Load Library" and Observe Console

Expected results: The Code shouldn't throw an Exception and the correct number parameters should be returned as part of the delegate's MethodInfo on either runtime
Actual results: In Console, there will be printed Exception:

"Failed to invoke delegate eith error: Number of parameters specified does not match the expected number.
UnityEngine.Debug:LogErrorFormat(String, Object[])
LoadLibraryMenu:LoadDll() (at Assets/Editor/LoadLibraryMenu.cs:66)"

Notes:
- This issue appears only on Windows Editor
- Cannot reproduce on macOS because Unity Editor does not load Library
- This works as expected when the Scripting Runtime Version is set to .NET 3.5 Equivalent

Reproduced on Unity 2018.2.15f1, 2018.2.20f1, 2018.3.6f1, 2019.1.0b4 and 2019.2.0a6
Not reproduced on Unity 2018.2.14f1
Regression on Unity 2018.2.15f1
