feat(revm, revme): gas inspector

[shekhirin]

Gas counting became a bit harder with the introduction of gas blocks composed during analysis. So GasInspector was introduced to make it easier to count remaining gas after each executed step.

Approach was adopted from

revm/bins/revme/src/statetest/trace.rs

Lines 10 to 17 in 1e25c99

	pub struct CustomPrintTracer {
	/// We now batch continual gas_block in one go, that means we need to reduce it ifwe want to get
	/// correct gas remaining. Check revm/interp/contract/analyze for more information
	reduced_gas_block: u64,
	full_gas_block: u64,
	was_return: bool,
	was_jumpi: Option<usize>,
	}

[gakonst]

is it possible this hurts performance meaningfully?

[shekhirin]

@gakonst you mean new GasInspector? I don't think so, it's just very simple math operations and O(1) lookups.

Thank you
