Support case insensitive bidder name in eidpermissions

[onkarvhanumante]

PR makes changes to support case insensitive bidder names in ext.prebid.data.eidpermissions.bidders.

As shown below bidder name appnexus is known name to PBS. But APPNEXUS is unknown. Prior to PR changes PBS would have error out with unknown APPNEXUS bidder name messgae. PR has implemented insensitive bidder name comparison in ext.prebid.data.eidpermissions.bidders

        "ext": {
            "prebid": {
                "data": {
                    "eidpermissions": [
                        {
                            "source": "source1",
                            "bidders": [
                                "APPNEXUS" //  sensitive bidder name
                            ]
                        }
                    ]
                }
          }

partially resolves #2400

I was testing this to make sure that the case style of the bidder name prior it being down cased, is the style we see in the response. Everything looks good except for one place, within seatbid[0].bid[0].ext.bidder, this field was still down cased. Just want to flag, to see if this is an issue.
