[7.x] Add support for arm64 macOS

[sirdharma]

This is a first pass at adding support for arm64 macOS.

I am opening this PR in order to start the discussion, alongside with the issue I opened earlier: #868.

On top of my head, this may raise a couple issues (but there may be more):

• What if the arm64_m1 version of ChromeDriver is not available for the targeted Chrome version? Do we want to fail or fallback?
• What if the user has a version of Chrome that is not an Universal app? I am unsure whether the arm64 version of ChromeDriver can start an Intel process.

I have tested this locally and it seems to work fine. The benefit is huge: running our Dusk test suite went from 7m 23s down to 3m 51s on my 13-inch M1 MacBook Pro.

Thank you!

Fail

@driesvints Thanks for that. I'll confirm the behavior as soon as I have access to an Intel Mac.

@driesvints I had all sorts of trouble installing an Intel version of Google Chrome, because of the way it enforces auto-updates on the user 🥲. I've also had my teammates (Intel Mac and Linux) try the branch and confirm that Dusk correctly installs the appropriate chromedriver, so I would say it's looking pretty safe 👍

Please let me know what you think. Thanks!

@sirdharma thanks for this. I'm going to put this one in draft for a bit longer until we've first merged #873

After that I'm going to have to ask you to rebase this PR with master.

[driesvints]

@sirdharma that PR is merged now. Can you rebase this one?

[sirdharma]

@driesvints Done.

[driesvints]

Perfect. Thanks @sirdharma!
