Pull Request Overview
This PR introduces non-generic tensor interfaces and updates tensor implementations to support basic operations such as index access via object indexers, memory pinning, and filling using object values. Key changes include:
- Replacing the generic IReadOnlyTensor<TSelf, T> with a non-generic IReadOnlyTensor interface.
- Introducing object-based indexers and methods for pinning backing memory.
- Updating tests to cover the new object API and memory pinning functionality.

| File | Description |
|---|---|
| src/libraries/System.Numerics.Tensors/src/System/Numerics/Tensors/netcore/IReadOnlyTensor.cs | Replaces the generic interface with a non-generic version and adds new properties/methods (Lengths, Strides, indexers, GetPinnedHandle). |
| src/libraries/System.Numerics.Tensors/tests/TensorTests.cs | Adds new tests for object-based filling, index access, and pinned memory handling. |
| src/libraries/System.Numerics.Tensors/src/System/Numerics/Tensors/netcore/ITensor.cs | Updates the ITensor interface to inherit from the non-generic IReadOnlyTensor and includes new signatures for indexers and Fill. |
| src/libraries/System.Numerics.Tensors/src/System/Numerics/Tensors/netcore/Tensor.cs | Adjusts the Tensor implementation to support the new non-generic interfaces and implements the GetPinnedHandle and object-based Fill methods. |
| src/libraries/System.Numerics.Tensors/ref/System.Numerics.Tensors.netcore.cs | Updates the reference assemblies to reflect changes in the interfaces and class signatures. |

Fixes #111968 and fixes #111966
Addes in gon-generic interfaces for tensors that let you do basic operations.
Also adds in the ability to pin the backing memory.
