Adds a new type of utility process that is set up to handle Windows OS objects. We are adding this process type to run Windows geolocation APIs but more services are expected to be included in it. The ILocation APIs have a race condition that would otherwise crash the main process. The ILocation work is in a later patch in the series. Depends on D155017 Differential Revision: https://phabricator.services.mozilla.com/D155018
