perf(core): reuse buffer in trie commits (WIP)

[SDartayet]

Motivation

Improving performance when adding new trie nodes.

Description

This PR introduces a vector used as a buffer for the RLP encode. Said vector is then drained when the contents are pushed into the accumulator for the RLP encodings of the node's children

Closes #3267
