Minimal D3D11 pt2

Follow-up to Minimal D3D11, adding instanced rendering. As before: An uncluttered Direct3D 11 setup & basic rendering primer / API familiarizer. Complete, runnable Windows application contained in a single function and laid out in a linear, step-by-step fashion. No modern C++ / OOP / obscuring cruft.

The main difference here is that the hollow cube is rendered using DrawIndexedInstanced (which saves a lot of vertices compared to the original, so model data is now small enough to be included in the source without being too much in the way), but also all trigonometry and matrix math is moved to the vertex shader, further simplifying the main code.

Each instance is merely this piece of geometry, consisting of 4 triangles:

I recently upgraded to Windows 11 and had to set up Visual Studio C++ again. A few things have changed in Windows 11 with the tiled window management and deeper Windows Terminal integration, so I ended up revisiting my usual VS setup and made a bunch of changes. I'm documenting them here for my own future benefit (yes, I do know about VS import/export settings) and on the off chance that anyone else might get some ideas for their own setup.

It should be mentioned that I'm a single monitor user (multimon gives me neck pain as I've gotten older) and the monitor I currently use is 25". A laptop screen can't really accommodate the 2x2 full screen layout I'm using as my default here, so when I'm on a laptop I only use the vertical layout out of necessity.
