Support builds via depot.dev

[jsierles]

This borrows code from dockerfileBuilder, but has some differences as depot is remote and can build and push to the fly registry directly.

The CLI arguments followed the style of the nixpacks flags.

To deploy using depot:

• flyctl deploy --depot

To run a machine:

• flyctl machines run --build-depot

Hello!

I'm trying to review this PR by checking if it works locally:
✅ 1. Check if go build works
-works great with go build -o bin/flyctl.exe .

❌ 2. Use the built flyctl.exe to run flyctl.exe deploy --depot in a local Laravel Fly App directory:
- running the command gives me an error:

/.../newapp$ /.../go/flyctl/bin/flyctl.exe  deploy --depot
==> Verifying app config
Validating /home/admin_kath/development/projects/php/tests/newapp/fly.toml
✓ Configuration is valid
--> Verified app config
==> Building image
==> Building image
Error: failed to fetch an image or build from source: error building: returned error 500 Internal Server Error: {"errors":[{"message":"You hit a Fly API error with request ID: 01J3ZWBYA2E6V29C7SB41NQ448-ams","extensions":{"code":"SERVER_ERROR","fly_request_id":"01J3ZWBYA2E6V29C7SB41NQ448-ams"}}],"data":{}}

   - just a note: running `fly deploy` in that local Laravel Fly App directory succeeds though
   - what can I do to make this command run successfully? Did I miss anything?

ah whoops. a secret accidentally got overridden with the incorrect value. just fixed that. deploying should work fine now :)

Awesome! I've re-run and the deploy succeeded with depot! 🎉

Here are the manual tests I've done to verify the commands work:

Test if the commands work locally within a Laravel Fly app's project directory

❓ flyctl deploy --depot
✅ Successfully deploys

admin_kath@__6:~/.../newapp$ /.../go/flyctl/bin/flyctl.exe deploy --depot

[+] Building 47.1s (22/22) FINISHED                 

❓ flyctl machines run --build-depot
✅ Successfully creates a new machine for the app

Check if the both commands work as expected in a CI environment

• Copied a compressed version of the local build of the PR's flyctl.exe to a repository
• Created a github workflow to use flyctl.exe deploy --depot and flyctl.exe machines run --build-depot here's a sample run
  **RESULT: Commands run successfully!
