[Feature Request] Implement IEquatable<T> on OrtTensorTypeAndShapeInfo

[vpenades]

Describe the feature request

it would be useful in some scenarios that OrtTensorTypeAndShapeInfo implements IEquatable<T> and associated GetHashCode to compare instances

struct OrtTensorTypeAndShapeInfo : IEquatable<OrtTensorTypeAndShapeInfo>
{
...
}

Describe scenario use case

I've found myself in a situation in which I have, I am using a Dictionary<OrtTensorTypeAndShapeInfo, LAMBDA> where the lambda is a specific funcion that knows how to operate on a tensor of that specific type and shape.

Unfortunately, because the OrtTensorTypeAndShapeInfo has a Shape array, the default equality is comparing the instances of the arrays and not the contents of the shape arrays.

implementing IEquality would fix that.
