inking-windows: Windows Ink integration

[nahkd123]

• Might depends on inking-api: Move back to Java 17? #2
• C++ binding that interacts with rtscom.h
• Find a way to cross-compile from Linux to Windows (might helps with CI; optional)
• Add API for checking if the tablet device is "virtual". Virtual device always reports pen position in pixels, rather than tablet's hardware position like OpenTabletDriver (OTD).

Windows Ink "driver" can be initialized like this:

long hWnd = 0L; // replace with window's handle
TabletDriver winink = new WindowsInkDriver(hWnd);

I don't want to touch FFAPI from Java 21 for this, because 1. there is JNI header for C++ and 2. user needs to install Java 21 and enable --enable-preview flag OR they can just install Java 22. (FYI: FFAPI was used for OTD because there is no good JNI interface for C# at the time of when I was writing this)

If possible, I might be able to do cmake cross-platform magic where a single C++ file works on Windows and Linux, which means inking-windows is not needed (and instead be replaced by "inking-impl" or something like that).

neither mingw nor cygwin provides RTSCOM.h, this is going to be painful to get Inking compiled on a single Linux container...

I think I'll go with C# instead of C++. COM wasn't always nice to work with in C++ for someone that haven't used COM like me.
