Add commontypes/resource-management/v3/managedidentity (Azure#15968)

* Add commontypes/resource-management/v3/managedidentity which models managed identity for services supporting both SystemAssignedIdentity and UserAssignedIdentity.

* Add a canonical SystemAssignedServiceIdentityType type definition which supports 'None', since that is required going forward. Also make the 'type' property required, since omitting it from the request would not be clear in intent.

* Add principalId and tenantId.
