Switch return type for OpCert signing request

[cecille]

Problem

I originally re-used the AttestationResponse type for the op cert
signing requests because they return data in the same format. This
was confusing, so adding another struct define with the same name.
Fixes: #15614

Change overview

Add a new type for op cert signing response and use that in the report.
