Add `-vs` and `-vscode` to build scripts

In microsoft/testfx, we have `-vs` as part of our `build.ps1`:

https://github.com/microsoft/testfx/blob/9f043c6725409d3acc9871983460cbf8a669c6c9/eng/build.ps1#L36-L61

And then we have `open-vs.cmd` in repo root:

https://github.com/microsoft/testfx/blob/main/open-vs.cmd

We are also adding `open-code.cmd` in https://github.com/microsoft/testfx/pull/5592

I suggest adding these in Arcade so that they are available for all repos under `eng/common`, then individual repos can add simple wrappers in repo root.
