[core] Tensor::data member preserve constness of tensor

[praasz]

Details:

• The Tensor::data function member returns const/non-const pointer to data depends if tensor object is constant.
• Add support to create tensor view for allocated host memory as read only.

Blocked by:

• Update tensor pointer cast openvino_contrib#952
• Use const pointers for const tensors openvino_tokenizers#450
• Update cast of tensor data pointer for const tensors openvino.genai#1966
• Correct use tensor and data pointer open_model_zoo#4005

Tickets:

• CVS-163832

Looks like we break source compatibility with this change?

The compilation errors will points where cast of tensor data pointer is done wrong (programing errors: missing const) from this perspective it will break compatibility.

To avoid compile errors with current data() member there is a need to introduce new member or overload data with some tag and mark current data() as deprecated or it will work as new implementation of pointer cast, but still there will be get non-const pointer to const tensors.

ok for core

I suppose we cannot merge this PR as is, because it breaks source compatibility (we saw it in GenAI, Tokenizers, OMZ and Contrib).

We need to make this change more smoothly
