Send consent data to Shared Id endpoint

Description

In EU, the id.sharedid.org/id endpoint requires consent data in order to return an id which is currently not being sent.

The parameters gdpr and gdpr_consent should be set as follows:

https://id.sharedid.org/id?gdpr=1&gdpr_consent=consent_string

Other information

prebid/shared-id#20
#6235

This should be fairly straight forward as getId already passes consentData:

Prebid.js/modules/userId/index.js

Line 644 in 97e5351

response = submodule.submodule.getId(submodule.config, consentData, storedId);

extendId needs to be modified to pass consentData as well though:

Prebid.js/modules/userId/index.js

Line 647 in 97e5351

response = submodule.submodule.extendId(submodule.config, storedId);
