fix(spec): track collision-burned gas in regular_gas_used

On CREATE/CREATE2 address collision the 63/64 gas allocation is
burned but was not added to regular_gas_used, leaving it invisible
to 2D block gas accounting. Per EIP-684 collision behaves as an
immediate exceptional halt, so the burned gas belongs in the regular
dimension.
