Pass device_id/device_type to web flow token approval url.

Pass device_id/device_type to web flow token approval url.

The issue is after enabling sending device_id for LST, IssueToken
endpoint started returning "issueAdvice": "consent" for scope marked
 with per_device_authorization_required:true.

The solution is to pass the same device_id/device_type to approval url.

Tests:
Tested that for LST with device_id consent screen is only shown once.
After restart access token is issued without user interaction.

Tested that for LST without device_id no consent screen is shown.
