Determines if the current tensor has any dimension where GetDimensionSpan(int) will iterate through tensors that would have IsDense be true.

Remarks
This does not include the last dimension, GetDimensionSpan(Rank - 1), as it always iterates 1 element at a time and would mean this property always returns true.
An example of a tensor which is not dense but which would have a dense dimension is a 2x2 Tensor where FlattenedLength: 4; Lengths: [2, 2]; Strides: [4, 1]. In such a scenario, the overall tensor is not dense because the backing storage has a length of at least 6 and so has 2 used elements, 2 unused elements, followed by the last 2 used elements. However, the two slices representing [0..1, ..] and [1..2, ..] would themselves be dense; thus GetDimension(0).GetSlice(n) will iterate dense tensors: FlattenedLength: 2, Length: [2], Strides: [1].
