Replace references to identity cards with identity document (fixes #9829)

[kentwilliams-stripe]

Summary

Instead of referring to an ID as "Identity Card" we use the term "Identity Document" to avoid confusion when only one type non-card identity is permitted.

Also remove unused definitions of stripe_back_of_id_document and stripe_front_of_id_document messages.

Motivation

Addresses #8511

• Added tests
• Modified tests
