It's possible that the web-sdk is loaded from within iframes, in which case
window.__tcfapiandwindow.__gppwon't be installed and consent won't be available at all to the SDK.In order to preserve consent handling in such case, this PR leverage the postMessage CMP APIs for gpp and tcf.
New helpers are introduced so that if the corresponding CMP proxy iframe is found in parent frames, a mocked window function is installed which will communicate with the iframe through the postMessage API.
This allows consumers like
getConsentto transparently look for and use__{cmpapi}function on window without having to know if it communicates directly or through the frame proxy with the CMP.
