Make it easier to build with VS Code and Visual Studio

[KeyWorksRW]

Description:

Building from CMake is fine for people who are used to building from a command line. On Windows, a lot of people are going to be using either Visual Studio Code or Visual Studio and they may not be familiar with building from a command line. It would would be helpful to add a document file that describes how to build from either of these IDEs, along with some additional notes about building from the command line on Windows when using MSVC.

Note that we have a building_notes.md file which is outdated since we now use a github action for building betas/release. It does, however, contain information about required changes to make for a release that should go into DEV_NOTES.md. It also contains a bit of information about configuring CMake that should be expanded as more general build information.

While we don't track the src/.vscode directory, we could certainly add a VSCode/ directory that contains various *.json file for use with VS Code. That way a dev could create a .vscode directory and copy the files into .vscode as a starting point.

Making files for Visual Studio is a bit trickier unless I can find a way to automate updating file list. So far I've had no luck convincing VS to actually use the CMakeLists.txt file that contains all the build information -- in spite of MS stating that the current version of VS supports CMake builds. In any event, it needs further investigation...

See #1188 and #1193 for issue/discussion about this.
