cyberrex5 416419ffde [PT Run] Refactoring: combined all NativeMethods.cs files for plugins… (#15807)
* [PT Run] Refactoring: combined all NativeMethods.cs files for plugins into Wox.Plugin/Common/Win32/

* Fixed spell check

* [PT Run] Changed NativeMethods.Helpers to Win32Helpers (seperate class) to not conflict with Microsoft.PowerToys.Settings.UI.Library.Helpers

* [PT Run] Renamed Constants.cs to ConstantsAndStructs.cs and moved all of them from NativeMethods.cs

* [PT Run] Merged ConstantsAndStructs.cs into NativeMethods.cs and renamed Constants to Win32Constants to avoid conflicting

* [PT Run] Added missing summaries + fixed missed refactored method

* [PT Run] Use using directive instead of alias + updated method call for .Net 6

* [PT Run] Fixed missed using alias + spell check
