This PR addresses one of the biggest performance issue with binary
tries: storing each internal node individually bloats the index, the
disk, and triggers a lot of write amplifications. To fix this issue,
this PR serializes groups of nodes together.
Because we are still looking for the ideal group size, the "depth" of
the group tree is made a parameter, but that will be removed in the
future, once the perfect size is known.
This is a rebase of #33658

This PR introduces a gasBudget struct to track the available gas for EVM
execution.
With the upcoming EIP-8037, multi-dimensional gas accounting will be
introduced, requiring multiple gas budget counters to be tracked
simultaneously. To support this, the counters are grouped into a gasBudget
structure.
This change is a prerequisite for internal refactoring in preparation
for EIP-8037.

This Pr implements some prerequisite changes for #34004 : split the
`CachingDB` into a `MerkleDB` and a `UBTDB`, so that very different
behaviors don't clash as much.
The transition isn't handled by this PR, but after talking to Gary we
agreed that `UBTDB` should receive another `triedb`, which will only be
loaded if the `Ended` flag is set to false in the conversion contract.
If this is too hard to achieve, it makes sense to load it regardless,
and then loading can be prevented at a later stage by adding a
`UBTTransitionFinalizationTime` in `ChainConfig`.

This is broken off of #31730 to only focus on testing networks that
start with verkle at genesis.
The PR has seen a lot of work since its creation, and it now targets
creating and re-executing tests for a binary tree testnet without the
transition (so it starts at genesis). The transition tree has been moved
to its own package. It also replaces verkle with the binary tree for
this specific application.
