Add a clear error message when creating an empty Constant

[p-wysocki]

Context

Current Constant implementation does not allow for creating empty Constants:
https://docs.openvino.ai/2023.0/openvino_docs_ops_infrastructure_Constant_1.html

Trying to do so results in a cryptic error message:

IndexError: index 0 is out of bounds for axis 0 with size 0

What needs to be done?

1. Add a clear error message for the user trying to create an empty Constant
   This can be done in either Python wrapper: https://github.com/openvinotoolkit/openvino/blob/master/src/bindings/python/src/openvino/runtime/opset1/ops.py#L334-L347
   Or in C++ to Python binding: https://github.com/openvinotoolkit/openvino/blob/master/src/bindings/python/src/pyopenvino/graph/ops/constant.cpp

It's up to you to decide where the error message implementation will be a good fit.

2. Make sure the error message appears
   This can be done either manually or by writing a test.

3. Create a Pull Request
