Add Cloud support for AvMessage

[thutto]

🚀 Feature request

Current Behavior

AvMessage grabs window.location.origin if available. This causes a cross domain error with cloud applications.

Desired Behavior

For Cloud Applications utilize the referrer if available.

Suggested Solution

Create a method in env-var to determine of we are a cloud app.
export function isCloud(windowOverride = window) { const options = getLocationComponents(windowOverride); return !!getCloudEnv(options); }

Modify the domain function of AvMessage to use referrer if we are cloud.
if (document.referrer && isCloud()) { const referrerAnchor = getLocation(document.referrer); return ${referrerAnchor.protocol}//${referrerAnchor.host}; }

Who does this impact? Who is this for?

This is for the Spaces Cloud Effort for the Digital Team.
