Description
accountTrieCache and storageTrieCache were introduced in this PR: #257, which is to improve performance. Actually the performance gain is quite limitted, as there is already dirty and clean cache for trie node.
And after big merge, these 2 cache can not be used when PBSS is enabled. So remove these code to simplify the logic.
