primitives: remove BlockHeader and Header reexport

[tcoratger]

Describe the feature

After the merge of alloy-rs/alloy#1302 and its inclusion over the next release of alloy, we can completely remove BlockHeader trait and Header reexport here

reth/crates/primitives-traits/src/header/mod.rs

Lines 12 to 73 in ed1de89

	use alloy_primitives::{Address, BlockNumber, B256, U256};
	/// Trait for extracting specific Ethereum block data from a header
	pub trait BlockHeader {
	/// Retrieves the beneficiary (miner) of the block
	fn beneficiary(&self) -> Address;
	/// Retrieves the difficulty of the block
	fn difficulty(&self) -> U256;
	/// Retrieves the block number
	fn number(&self) -> BlockNumber;
	/// Retrieves the gas limit of the block
	fn gas_limit(&self) -> u64;
	/// Retrieves the timestamp of the block
	fn timestamp(&self) -> u64;
	/// Retrieves the mix hash of the block
	fn mix_hash(&self) -> B256;
	/// Retrieves the base fee per gas of the block, if available
	fn base_fee_per_gas(&self) -> Option<u64>;
	/// Retrieves the excess blob gas of the block, if available
	fn excess_blob_gas(&self) -> Option<u64>;
	}
	impl BlockHeader for Header {
	fn beneficiary(&self) -> Address {
	self.beneficiary
	}
	fn difficulty(&self) -> U256 {
	self.difficulty
	}
	fn number(&self) -> BlockNumber {
	self.number
	}
	fn gas_limit(&self) -> u64 {
	self.gas_limit as u64
	}
	fn timestamp(&self) -> u64 {
	self.timestamp
	}
	fn mix_hash(&self) -> B256 {
	self.mix_hash
	}
	fn base_fee_per_gas(&self) -> Option<u64> {
	self.base_fee_per_gas.map(|base_fee| base_fee as u64)
	}
	fn excess_blob_gas(&self) -> Option<u64> {
	self.excess_blob_gas.map(|excess_blob_gas| excess_blob_gas as u64)
	}
	}

We can then import everything from alloy directly when needed around the codebase.

This issue is stale because it has been open for 21 days with no activity.

[mattsse]

we likely want a smaller trait for this because we only need a subset from this alloy trait
