This involved moving the logic into ProcessIsolation.cpp, closer to the rest of the process selection logic. The existing method is preserved, to be used as a convenience for callers. As the new logic is closer to the rest of the process selection logic, this also simplifies the remote type parsing logic to perform direct string compares against the remoteType's site-origin. If origin keying of processes is added in the future, this will likely need to be updated to handle that case. Differential Revision: https://phabricator.services.mozilla.com/D241879
