Migrate to Electron 11

[warpdesign]

What needs to be done:

• update drivelist to 9.2.1 (some changes may be needed: the API appears to have changed)
• upgrade Electron to version 11
• update build process to allow building ARM64 builds for Windows, Linux & Mac (see Plans to Support Apple Silicon builds? electron-userland/electron-builder#5392 (comment) & feat:(mac): Apple Silicon builds (arm64)  electron-userland/electron-builder#5426)

Electron 11 is a bit... behind to say the least. The latest version is 19, so that would be over 8 releases behind. And only the last 3 Electron releases get security patches!

Indeed. I'm going to upgrade to Electron 12 but this will require quite a lot of work: I want to leave enabled most security/sandboxing options so this will require some work.

When it's done, I think upgrading to more up to date versions of Electron won't be a problem.

I'll leave the ARM Mac version for now.
