[Py OV] Move ie_api.py and exceptions.py files to openvino module (op…

…envinotoolkit#28007)

### Details:
- move `runtime/ie_api.py` and rename it to `_ov_api.py` as ie_api is a
legacy name.
- add `runtime/ie_apy/__init__.py` as proxy
- update `openvino/__init__` to import from `_ov_api.py`.

- move `runtime/exceptions.py` and add proxy in `runtime`
- update `test_ovdict` to use `OVDict` defined in
`openvino.runtime.utils.data_helpers`
- update `tensor_from_file` import in `openvino/__init__.py`. This
function is located in `openvino.runtime.utils.data_helpers`

Part of `openvino.runtime` deprecation

### Tickets:
 - [CVS-129459](https://jira.devtools.intel.com/browse/CVS-129459)
