[PS-1854] Split folder service back/foreground (#4209)

* Split folder service back/foreground

Also splits for folderApiService, since that depends on folderService.

TODO: this split will need to be done for any dependents of a split
service.

* Prefer popup-specific services VaultFilterService

* Prefer popup-specific services i18n

* Prefer popup-specific services configService

* StateService is required for browserSync

* Add Policy Api Service

* Remove unused orgService from PolicyApiService

* Fixup missed dependency

* Attach cryptography services in popup context

* Improve session syncer initialization
