trie, core/state: Nyota EIP-6800 & EIP-4762 spec updates (#30357)

Browse Source 
This PR implements changes related to
[EIP-6800](https://eips.ethereum.org/EIPS/eip-6800) and
[EIP-4762](https://eips.ethereum.org/EIPS/eip-4762) spec updates.

A TL;DR of the changes is that `Version`, `Balance`, `Nonce` and
`CodeSize` are encoded in a single leaf named `BasicData`. For more
details, see the [_Header Values_ table in
EIP-6800](https://eips.ethereum.org/EIPS/eip-6800#header-values).

The motivation for this was simplifying access event patterns, reducing
code complexity, and, as a side effect, saving gas since fewer leaf
nodes must be accessed.
