Collect device_id from arkose payload

What does this MR do and why?

Collect device_id from arkose payload

part of: https://gitlab.com/gitlab-org/modelops/anti-abuse/team-tasks/-/issues/350

How to set up and validate locally

1. Enable hard email confirmation

2. Enable Identity verification and arkose API access. API keys can be found in 1Password under "ArkoseLabs API keys". You will need to use the production keys, as the feature is not accessible on dev keys at the moment (slack discussion).

$ rails console
> Feature.enable(:identity_verification)
> Feature.enable(:arkose_labs_signup_challenge)
> ApplicationSetting.first.update({ arkose_labs_public_api_key: '****', arkose_labs_private_api_key: '****', arkose_labs_namespace: 'client' })

1. Register as a new user

2. Confirm user has a arkose_device_id custom attribute: User.last.custom_attributes.where(key: 'arkose_device_id')

3. Remove prod keys from your system: ApplicationSetting.first.update({ arkose_labs_public_api_key: 'bob', arkose_labs_private_api_key: 'marley') })
