[DML EP] DML Graph Serialization Bug (#19748)
### Description
This pull request addresses several issues:
- The DML Graph's nodes were not sorted in a topologically ordered
sequence, leading to crashes during deserialization when a child node
preceded its parent node. This PR resolves this issue by implementing a
topological sorting algorithm before serialization.
- During the `RemoveUnconnectedNodes` process:
- we update `intermeidateEdge.FromNodeIndex`. Additionally, we must
update `intermediateEdge.Name` when it includes
`intermediateEdge.FromNodeIndex`, as serialization/deserialization
heavily relies on edge names.
- we also eliminate unused edges. Consequently, we must erase inputs
(now unused) from corresponding maps
`serializedGraphInputIndexToSubgraphInputIndex` and
`serializedGraphLargeConstantNameToSubgraphInputIndex`.
### Motivation and Context
Why is this change required? What problem does it solve?
There are few ONNX Zoo public models which were crashing during
deserialization.
