core/state: move UpdateContractCode before the trie hash is computed (#27853)

Browse Source 
Context: The UpdateContractCode method was introduced for the state storage commitment
schemes that include the whole code for their commitment computation. It must therefore be called
before the root hash is computed at the end of IntermediateRoot.

This should have no impact on the MPT since, in this context, the method is a no-op.
