tests: update tests (#26314)

Browse Source 
This PR builds on #26299, but also updates the tests to the most recent version, which includes tests regarding TheMerge.

This change adds checks to the beacon consensus engine, making it more strict in validating the pre- and post-headers, and not relying on the caller to have already correctly sanitized the headers/blocks.

## EVM state transition tool # EVM tool
The EVM tool provides a few useful subcommands to facilitate testing at the EVM
layer.
* transition tool (`t8n`) : a stateless state transition utility
* transaction tool (`t9n`) : a transaction validation utility

### Command line params #### Command line params
Command line params that need to be supported are
```

```
#### Objects
The transition tool uses JSON objects to read and write data related to the transition operation. The
following object definitions are required.
##### `alloc`
The `alloc` object defines the prestate that transition will begin with.
```go
// Map of address to account definition.
type Alloc map[common.Address]Account
// Genesis account. Each field is optional.
type Account struct {
Code []byte `json:"code"`
Storage map[common.Hash]common.Hash `json:"storage"`
Balance *big.Int `json:"balance"`
Nonce uint64 `json:"nonce"`
SecretKey []byte `json:"secretKey"`
}
```
##### `env`
The `env` object defines the environmental context in which the transition will
take place.
```go
type Env struct {
// required
CurrentCoinbase common.Address `json:"currentCoinbase"`
CurrentGasLimit uint64 `json:"currentGasLimit"`
CurrentNumber uint64 `json:"currentNumber"`
CurrentTimestamp uint64 `json:"currentTimestamp"`

## About Ommers #### About Ommers
Mining rewards and ommer rewards might need to be added. This is how those are applied: Mining rewards and ommer rewards might need to be added. This is how those are applied:
- `block_reward` is the block mining reward for the miner (`0xaa`), of a block at height `N`. - `block_reward` is the block mining reward for the miner (`0xaa`), of a block at height `N`.
- For each ommer (mined by `0xbb`), with blocknumber `N-delta` - For each ommer (mined by `0xbb`), with blocknumber `N-delta`
- (where `delta` is the difference between the current block and the ommer) - (where `delta` is the difference between the current block and the ommer)
- The account `0xbb` (ommer miner) is awarded `(8-delta)/ 8 * block_reward` - The account `0xbb` (ommer miner) is awarded `(8-delta)/ 8 * block_reward`
- The account `0xaa` (block miner) is awarded `block_reward / 32` - The account `0xaa` (block miner) is awarded `block_reward / 32`
To make `state_t8n` apply these, the following inputs are required: To make `t8n` apply these, the following inputs are required:
- `state.reward` - `--state.reward`

The transition tool uses JSON objects to read and write data related to the transition operation. The
following object definitions are required.
##### `alloc`
The `alloc` object defines the prestate that transition will begin with.
