Proposal: enforce eip-155 to protect against replay

Current behavior:

Right now, non-eip155 txs are still accepted, which opens room for replaying old ethereum tx on ethermint, similar to what happened on optimism recently.

Desired behavior:

Reject those txs and close the room for a potential attack.

Use case: [Why is this important (helps with prioritizing requests)]

Requests may be closed if we're not actively planning to work on them.

Agree, we introduce a parameter in the EVM to disable the LegacyTx type. This should be checked in the AnteHandler so that the user doesn't spend gas
