Update base for Update on "[ET-VK] Implementation of to_dim_order_copy"

Title says it all!

Previously, to_dim_order_copy was handled by removing the op. However, this is not possible if the op is modifying the dtype of the original tensor, so these instances of the op would be skipped by the partitioner.

This diff adds an implementation dtype conversion, which allows to_dim_order_copy to be lowered.
