it doesn't look like trieKeysCache can ever be null in this case

do we really need to cache trieKeys? seems like the only expensive thing to cache would be the 31 byte stem address, and we can just suffix it at-will. It should reduce the cache size and might make for a better performing key generation on execution (since the stem would be cached and not regenerated if the slot key or code keys were not pre-calculated)

I updated the code in order to save stem , this one depends on this besu-verkle-trie PR hyperledger/besu-verkle-trie#64 |

PR description
Currently, trie keys generation will gather all transactions data and generate a single large batch of trie keys at once.
However, there are already mechanisms implemented in Besu to preload those trie keys in a background thread during block processing.
This PR generates the different triekeys in the background in order to have a maximum of triekeys already calculated at the end of the block
