Remove extra Total difficulty argument for execution

[mattsse]

Describe the feature

currently we always provide block + TTD for execution:

reth/crates/evm/execution-types/src/execute.rs

Lines 5 to 12 in f82a20a

	/// A helper type for ethereum block inputs that consists of a block and the total difficulty.
	#[derive(Debug)]
	pub struct BlockExecutionInput<'a, Block> {
	/// The block to execute.
	pub block: &'a Block,
	/// The total difficulty of the block.
	pub total_difficulty: U256,
	}

this is only relevant for pre-merge blocks because the hardfork is determined by the total difficulty.

this only affects sepolia+mainnet.

it would simplify a lot of things if we could only rely on the Block as input.
since all of these transition blocks are finalized and we sync in reverse we should be able to use the hardcoded transition blocks in the chainspec:

reth/crates/ethereum-forks/src/hardfork/ethereum.rs

Lines 74 to 93 in f82a20a

	pub const fn mainnet_activation_block(&self) -> Option<u64> {
	match self {
	Self::Frontier => Some(0),
	Self::Homestead => Some(1150000),
	Self::Dao => Some(1920000),
	Self::Tangerine => Some(2463000),
	Self::SpuriousDragon => Some(2675000),
	Self::Byzantium => Some(4370000),
	Self::Constantinople | Self::Petersburg => Some(7280000),
	Self::Istanbul => Some(9069000),
	Self::MuirGlacier => Some(9200000),
	Self::Berlin => Some(12244000),
	Self::London => Some(12965000),
	Self::ArrowGlacier => Some(13773000),
	Self::GrayGlacier => Some(15050000),
	Self::Paris => Some(15537394),
	Self::Shanghai => Some(17034870),
	Self::Cancun => Some(19426587),
	_ => None,
	}

and use that when we determine the appropriate revm specid:

reth/crates/ethereum/evm/src/config.rs

Line 28 in f82a20a

pub fn revm_spec(chain_spec: &ChainSpec, block: &Head) -> revm_primitives::SpecId {

so that:

reth/crates/ethereum-forks/src/forkcondition.rs

Lines 84 to 87 in f82a20a

	/// - The condition is satisfied by the block number;
	/// - The condition is satisfied by the timestamp;
	/// - or the condition is satisfied by the total difficulty
	pub fn active_at_head(&self, head: &Head) -> bool {

no longer needs to check any total difficulty input
