Windows VS 2022 Execute Build Command in VS Code

devcmd.bat is used to run a command within the context of a Visual Studio development environment in VS code. An environment variable, DEV_MODE, is used to indicate if it's being used to execute tasks or is meant to be interactive, and thus launch a Git Bash interactive shell.
