feat(contacts): use bitmap for skipped messages

[zimpha]

Purpose or design rationale of this PR

This PR use a bitmap to keep track the status of skipped and dropped messages. It shall save a lot of gas compared to previous method.

Why previous method failed?

Gas Refunds

Some opcodes can trigger gas refunds, which reduces the gas cost of a transaction. Gas refunds are applied at the end of a transaction. If a transaction has insufficient gas to reach the end of its run, its gas refund cannot not be triggered, and the transaction fails. With the introduction of the London hardfork, two aspects of gas refunds changed. First, the limit to how much gas can be refunded is lowered from half of the total transaction cost, to one fifth of the total transaction cost. Second, the SELFDESTRUCT opcode cannot trigger gas refunds, only SSTORE.
