* [PM-3753] Update desktop language handling
* Remove i18n service import aliases
* Validate the provided locale before loading it
* Support underscores in locales
This PR wires up a polyfill for window.ipc which allows us to progressively migrate the codebase to a format which supports context bridge. This avoids a big bang effort where every non sandboxed call has to be migrated before we can run the code.
Once all calls to node modules are removed from the renderer and only exists in preload.ts. We will turn on context isolation and use the context bridge for communication instead.
