9a154229 - Fix rotary embedding to follow spec on attribute constraints (#26044)

Fix rotary embedding to follow spec on attribute constraints (#26044) ### Description <!-- Describe your changes. --> `num_heads` is not necessarily required from users when input shape is 4D. ### Motivation and Context <!-- - Why is this change required? What problem does it solve? - If it fixes an open issue, please link to the issue here. --> To follow ONNX spec, https://github.com/onnx/onnx/blob/main/docs/Operators.md#RotaryEmbedding, the original constraints on attributes were wrong. NOTE: 3 rotary embedding tests are expected to be wrong until next release.
