b77a6cda - squeeze and unsqueeze operators for the dnnl execution provider (#9798)

squeeze and unsqueeze operators for the dnnl execution provider (#9798) * Implementaiton of Squeeze op for dnnl ep Signed-off-by: George Nash <george.nash@intel.com> * Implementaiton of Unsqueeze op for dnnl ep Tests were added to the unsqueeze_op_test to test Unsqueeze op with a scalar input. The OneDNN (dnnl) ep automatically converts scalars to a one dimentional tensor. For most operations this causes no problems. However, for Unsqueeze the difference between a scalar vs. tensor couldn't be ignored. A IsScalar member function was added to the DnnlSubgrapPrimitive class that will return true if the ORT tensor was a scalar type. IsScalar() is then used inside the Unsqueeze code. updated the squeeze node capability to only accept ConstantInitializer inputs. All unsqueeze op tests that tested opset 13 now run with and without constant initializers. Signed-off-by: George Nash <george.nash@intel.com>
