added aten::take, aten::str and aten::Delete, but unable to write their tests

[vijaykr338]

Details:

I was able to implement aten::take and aten::Delete function,

but aten::str posed really high difficult, i was only able to partially implement the it

currently, my implementation works for constant tensors, but for dynamic tensors, it currently stores shape and dtype for later use in debugging.

I have another question, how do you write tests for functions which are not implemented in Aten library yet?

I was able to write test cases for aten::take by following examples existing pytest files in the PyTorch layer tests folder.

but when I did the same for Delete and str, they consistently gave error

this is my first contribution to openVINO, I would greatly appreciate any guidance or assistance.
