Networking Sign Up Pane (Native): Add back auto-focus

[carlosmuvi-stripe]

Summary

• Replaces activity resizing by insets (keyboard now smoothly animates)
• On signup pane, keeps bottom panel behind keyboard
• Focuses on email when empty
• Focuses on phone when email prefilled, but no phone prefilled
• Does not focus when both fields prefill.

Motivation

:notebook_with_decorative_cover:  Networking Sign Up Pane (Native): Add back auto-focus :globe_with_meridians:  BANKCON-10945

On networking sign up pane:

1. if user has no email, we will auto-focus the keyboard on email and the "Not Now" button will be behind the keyboard (user can still easily dismiss keyboard or press the "X" button)
2. if user has no phone (but prefill email), we will auto-focus the keyboard on phone (other details apply as above ^)
3. if we prefill both, we don't auto-focus

PR's that removed it:

1. email: https://github.com/stripe/stripe-ios/pull/2526
2. phone: https://github.com/stripe/stripe-ios/pull/2528
