IDMLDevive::CreateOperater, with DML_OPERATOR_GEMM operator type and the channel count of ATensor bigger than 65535 return E_INVALIDARG

Hi,
We using DML EP of onnxruntime and got an error on an Matmul node. After some debug we found that it was IDMLDevive::CreateOperater, with DML_OPERATOR_GEMM operator type and the channel count of ATensor shape is bigger than 65535 the IDMLDevive::CreateOperater will return E_INVALIDARG (We test the input shape {65536, 1, 256}).

microsoft/onnxruntime#20742 someone else may got the same error.

Any one known is that a limitation of 65535 channel count?
Thanks.
