[extint]

This Pull Request:

Updates the implementation of Binary and Unary Operators to parse input tensors with parametric shapes, such as {batch_size1, dim1}. The method to initialize the output tensor shape can be further improved in the future.

Changes or Fixes:

• Updated implementation in the respective ROperator files to handle parametric shapes.
• Added tests as well as models for the same.

Checklist:

• [x] Tested changes locally
• [ ] Updated the documentation (if necessary)
