Increase the size of the webauthn_credential credential_id field (#18739) 

Unfortunately credentialIDs in u2f are 255 bytes long which with base32 encoding
becomes 408 bytes. The default size of a xorm string field is only a VARCHAR(255)

This problem is not apparent on SQLite because strings get mapped to TEXT there.

Fix #18727
