[FE IR] IR de-serializer sets Result tensor names when parsing model (#…

…28105)

### Details:
- The model after read by IR frontend shows models output tensors names
as Nodes connected to Result's. But by default this names are not
dedicated Results name which can cause during pre-post processing that
names stay on node and will disapear as model output names. To fix set
the names as Results names so during transformations they will stay as
model's output names.
- Fix NPU test which reports `Attempt to get a name for a Tensor without
names`
