WebAuthn have updated their specification to set the maximum size of the
CredentialID to 1023 bytes. This is somewhat larger than our current
size and therefore we need to migrate.
The PR changes the struct to add CredentialIDBytes and migrates the CredentialID string
to the bytes field before another migration drops the old CredentialID field. Another migration
renames this field back.
Fix#20457

- Completely remove U2F support from 1.18.0, 1.17.0 will be the last
release that U2F is somewhat supported. Users who used U2F would already
be warned about using U2F for a while now and should hopefully already
be migrated. But starting 1.18 definitely remove it.
