trie: rename trie class to MerklePatriciaTrie

[gabrocheleau]

This PR renames the Trie class to MerklePatriciaTrie. This aligns with the modularization of state management (i.e. MerkleStateManager & VerkleStateManager) and data structure agnosticism.

I wasn't sure whether to name it "Tree" or "Trie" and decided to go with what was on the ethereum.org docs: https://ethereum.org/en/developers/docs/data-structures-and-encoding/patricia-merkle-trie/

So, to make the picture complete: the old pre-monorepo package was called merkle-patricia-tree, so now we have everything in to confuse people to the max. 😂

Anyhow: I just read up again a bit on Trie vs Tree and came to the conclusion that trie is indeed the more correct term here. So that would be my tendency as well.

I thought about package renaming as well couple of weeks ago, and I think we should consequently do. If aligned with the class name that would be:

• MerklePatriciaTrie
• @ethereumjs/merklepatriciatrie

One thing where I am not totally out of sympathy is to at least give it some quick thought if MPT (and @ethereumjs/mpt might also be enough in this case and shorter and easier to write down, this is such a common naming in the Ethereum world that this might be enough as well.

That would be:

• MPT
• @ethereumjs/mpt

And last but not least. Maybe it's also ok to not fully align class + package name. I personally e.g. do not really like the long package name from above. So one option might also be:

• MerklePatriciaTree
• @ethereumjs/mpt

(I think this might be my favorite, but have not very strong preferences on all)

I think my favorite is also the latter (explicit MerklePatriciaTree for the class, mpt for the package). Generally not a big fan of acronyms as I find they increase barrier to entry, but in the context of a package name I think it's fine & more concise.

Side note. If we decide to do a package renaming, I would do it in a separate PR, as I feel such a major task deserves is own dedicated PR.
