feat: Optional coinbase tip

[clabby]

Overview

Adds a new feature flag, optional_coinbase_tip CfgEnv option, disable_coinbase_tip, that allows for disabling the tip to coinbase during transaction finalization. This option will be used in https://github.com/anton-rs/op-reth to support the Regolith hardfork.

Can you do it without a feature flag, this option can be generally useful.

And (maybe not related) but is this line okay to stay, loading coinbase address as warm if coinbase does not receive a fee:

revm/crates/revm/src/evm_impl.rs

Lines 108 to 115 in 64b0874

	// load coinbase
	// EIP-3651: Warm COINBASE. Starts the `COINBASE` address warm
	if GSPEC::enabled(SHANGHAI) {
	self.data
	.journaled_state
	.initial_account_load(self.data.env.block.coinbase, &[], self.data.db)
	.map_err(EVMError::Database)?;
	}
