chore: remove 7685 request variants

[mattsse]

these got removed and replaced with a general purpose request blob

[onbjerg]

can also rm these:

alloy/crates/eips/src/eip7002.rs

Lines 30 to 38 in b4a435d

	pub struct WithdrawalRequest {
	/// Address of the source of the exit.
	pub source_address: Address,
	/// Validator public key.
	pub validator_pubkey: FixedBytes<48>,
	/// Amount of withdrawn ether in gwei.
	#[cfg_attr(feature = "serde", serde(with = "alloy_serde::quantity"))]
	pub amount: u64,
	}

alloy/crates/eips/src/eip7251.rs

Lines 25 to 32 in b4a435d

	pub struct ConsolidationRequest {
	/// Source address
	pub source_address: Address,
	/// Source public key
	pub source_pubkey: FixedBytes<48>,
	/// Target public key
	pub target_pubkey: FixedBytes<48>,
	}

alloy/crates/eips/src/eip6110.rs

Lines 20 to 33 in b4a435d

	pub struct DepositRequest {
	/// Validator public key
	pub pubkey: FixedBytes<48>,
	/// Withdrawal credentials
	pub withdrawal_credentials: B256,
	/// Amount of ether deposited in gwei
	#[cfg_attr(feature = "serde", serde(with = "alloy_serde::quantity"))]
	pub amount: u64,
	/// Deposit signature
	pub signature: FixedBytes<96>,
	/// Deposit index
	#[cfg_attr(feature = "serde", serde(with = "alloy_serde::quantity"))]
	pub index: u64,
	}

we just need the addresses + bytecode from these now, not even the request type constants, since this is determined by the position of the request in the Requests struct anyway
