eb24617d - Add ability to get symbolic dimension info for graph inputs and outputs. (#2051)

Add ability to get symbolic dimension info for graph inputs and outputs. (#2051) * Add ability to get symbolic dimension info for graph inputs and outputs. WIP to get initial feedback. * Fix linxu build error. Update C# API and add unit test * Clarify the two different ways Tensor shape and type info is created. One is from concrete values and one is from a type proto where symbolic dimensions may exist. Doing so allows a change to default to empty strings for the symbolic dimensions if not provided.
