[Feature Request] Support for Int64 datatype for shape tensor in Expand Op in ORT-QNN EP

[aparmp-quic]

Describe the feature request

Currently Int64 shape tensor is not handled in Expand Op builder and below error is thrown: expand_op_builder.cc. Support is required to cast and handle this datatype in ORT QNN EP.

Describe scenario use case

Currently we are getting below error if the input model has Int64 as shape tensor in Expand node.

[V:onnxruntime:, qnn_execution_provider.cc:521 onnxruntime::QNNExecutionProvider::GetSupportedNodes] Validation FAILED for 1 nodes in NodeUnit (Expand) :

	Operator type: Expand Node name: Expand_1 Node index: 1

	REASON : Type not supported.

QNN cast didn't support int64 type on HTP previously. They added that type recently, we can fix it by inserting cast op. Another walk around is to change the model to use int32 data type if it's urgent for you.
