✨Callout vendor update: adding gdpr_consent and account to Prebid Ser…

…ver urls (#24620)

* adding gdpr_consent to Prebid Server urls

Prebid Server now supports taking the gdpr_consent parameter on the AMP endpoint.

The assumption I'm making here is that the consent string is available to callout vendors as ATTR(consentString) - @zhouyx, can you confirm? This is based on info from https://github.com/ampproject/amphtml/blob/master/extensions/amp-consent/integrating-consent.md

* using CONSENT_STRING macro

* tweak format

* linting

* adding account parameter to prebid server string
