Visual Assist support for Visual Studio 2022 Previews!

Visual Studio (VS) 2022’s main change—and it’s a significant one—is that it will become a 64-bit process. Since Visual Assist (VA or VAX) runs as a plugin, in-process, we needed to build a 64-bit version of our plugin DLL. Those who have upgraded 32-bit code to 64-bit code before know that, even in well-architected code, it takes some work even just to review code to ensure it is correct. In addition, the new version adds and modifies a number of APIs we rely on to interact with the IDE.
