Remove u2f implementation

For a while now WebAuthn has replaced u2f.
And since web-vault v2.27.0 the connector files for u2f have been removed.
Also, on the official bitwarden server the endpoint to `/two-factor/get-u2f` results in a 404.

- Removed all u2f code except the migration code from u2f to WebAuthn
