Replace path with pathe

[AndreasArvidsson]

This is a simple way of getting rid of node path references in common and engine. I thought it best to also replace it in vscode so we don't have different implementations for path in the bundle. I guess for things like running tests and ours setup scrips then just using node path is probably fine? I could go either way.

I think we're on the same page that any references to path in the engine are a smell, but this is a fine way forward for now

Totally in agreements there
