Award criteria breakdown: add awardCriteria at tender level

[yolile]

We would need a different field name, for example, awardCriteriaBreakdown. We need to add this field only because current OCDS 1.1 limitations, as in OCDS 1.2, we will recommend always using at least one lot open-contracting/standard#891

@yolile for which publication is this for?

[yolile]

This was for the SPP extension and use cases. From a Slack thread: "Concurrently, publishers should model the selection and award criteria using the extensions that allow a breakdown. That way, an analyst can determine the weight assigned to SSP criteria."

Noting that in open-contracting/standard#891 (comment) it was decided to postpone the recommendation to always use at least one lot to 1.3 rather than attempt to introduce it in 1.2
