chore(cleanup): Remove EIP-7918 related functions and EIP file

[0xMushow]

While reviewing EIP-7918 and after discussing it with @rakita, it makes sense to remove this file:

revm/crates/primitives/src/eip7918.rs

Lines 1 to 6 in 784d30d

	//! EIP-7918: Blob Base Fee Bounded by Execution Cost
	//!
	//! Constants for blob base fee calculation with execution cost bounds.
	/// Minimum base fee for blobs, if price of the blob is less than this value, this value will be used.
	pub const BLOB_BASE_COST: u64 = 2_u64.pow(14);

Also, to perform some cleanup within this file (some functions are deprecated, not relevant anymore):

revm/crates/context/interface/src/block/blob.rs

Lines 43 to 130 in 784d30d

	/// Calculate this block excess gas and price from the parent excess gas and gas used
	/// and the target blob gas per block.
	///
	/// These fields will be used to calculate `excess_blob_gas` with [`calc_excess_blob_gas`] func.
	#[deprecated(
	note = "Use `calc_excess_blob_gas` and `BlobExcessGasAndPrice::new` instead. Only works for forks before Osaka."
