Install Python during windows setup and add new Visual Studio Build tools components

[iangmaia]

To fix the error seen in Automattic/studio#1594 (build), this PR implemented:

• Python installation during the Windows setup so that it can be used by npm install scripts
• Addition of native compilation components to Visual Studio Build Tools

Being tested via Automattic/studio#1608

---

• I have considered if this change warrants release notes and have added them to the appropriate section in the CHANGELOG.md if necessary.

@AliSoftware I think I addressed all the points. I struggled a bit with the unit tests later but everything seems to be finally working now 😌

I'm guessing the reason why this is controlled by an env var and not a flag (aka param { [switch] … }) like the others is because the skipping is only used for the tests so far?

But that made me wonder if the studio jobs running the Unit Tests might also not need the cert and want to skip it 🤔 💭

Yes, that's the case so far. Also, this seemed more like a configuration rather than an API argument so the env var felt more appropriate.

Good question. Imagining it still compiles the tested app in some way, perhaps they're still needed? But we can definitely try 👍
