Request: do not fail on eidPermissions to unknown bidder

[patmmccann]

We recently saw in a PBS-Go response: Invalid request: request.ext.prebid.data.eidpermissions[0] contains unrecognized bidder "ttd"

Could we consider not being so strict on unknown bidders?

Related: https://github.com/prebid/Prebid.js/pull/12571 may sometimes put client side bidders in the eidPermissions array

Approved by the committee.

Instead of failing on unknown bidders, please add a warning when in debug mode. No need for metrics or logs.

Done in PBS-Java 3.19
