feat: return deleted resources object from submitChanges

[kanikasharma97]

This PR aims to enhance the handling of deleted resources during the submit changes process. Currently, when a resource is deleted, only a status code is returned from the API without providing any details regarding the deleted resource. This PR addresses this limitation by introducing improvements in two key scenarios:

1. Handling Individual Resource Deletion:

   • Before submitting changes, the list of deleted resources is fetched in getRemovedResourcesObject method in FHIRModel.js
   • Upon successful deletion, it is ensured that the details of the deleted resources are returned along with the response.

2. Handling Partial Deletion:

   • In cases where multiple resources are being deleted and only partial deletion is successful, the details of the resource(s) for which deletion was successful iS gathered through newly introduced method getsIdFromOperationOutcome located in FHIRUtility.js.
   • Only the details of the successfully deleted resource(s) are returned as part of oError.resources.
