Keep the order of keys in cost models

[cffls]

Since plutus v3, sorting cost models based on the lexicographical of keys would result in wrong script data hash. We can assume the cost model from the chain context could be directly used without any sorting.

• The cost model keys are still being sorted in the CBOR branch, while the non-CBOR branch now preserves the original order. Confirm if both branches should use the same ordering for consistency.

cm = IndefiniteList([cost_model[k] for k in sorted(cost_model.keys())])
