core/state, light, trie: add UpdateContractCode to the Trie interface (#27476)

Browse Source 
Verkle trees store the code inside the trie. This PR changes the interface to pass the code, as well as the dirty flag to tell the trie package if the code is dirty and needs to be updated. This is a no-op for the MPT and the odr trie.
