Consent Management: make getTCData container object on static consent optional

[patmmccann]

Type of issue

Bug

Description

IABTL Action Plan likely will deprecate getTCData. Whether or not this happens, it is recommended not to use it. Let's immediately remove all references to it from the project. Luckily most references are just in unit tests, as consentManagement.js only uses it in the case of static consent

Tagging #8539 as this change is breaking

https://docs.prebid.org/dev-docs/modules/consentManagement.html example 3 will need to change

I am not sure this is worth the breaking change. getTCData appears to be a remnant from TCFv1, it's not useful anymore, but forcing a rename to something else seems to me like pure friction with no advantage.

[dgirardi]

Agreed offline that we should make the getTCData configuration "container" optional, e.g. support both gdpr: {consentData: {getTCData: {...}}} and gdpr: {consentData: {...}}

just for notetaking, we took care of https://github.com/InteractiveAdvertisingBureau/GDPR-Transparency-and-Consent-Framework/pull/334/files here
