cypress run should create a new browser profile per run

[brian-mann]

For users wanting to run multiple Cypress processes on the same machine - we should create a new browser profile when running to completion with cypress run.

This would prevent those browser instances from sharing the same state like cookies, local storage, indexdb, etc.

We'll need to write to a temporary folder in os.tmp() but also use the special tmp module which has process.exit hooks to cleanup folders immediately.

We will not do this for cypress open. That will always use the default profile, which enables users to do things like install extensions and preferences for how they like to use their browser.
