There was a problem hiding this comment.
Note: BuildBlock still verifies unique inputs (https://github.com/ava-labs/avalanchego/blob/verify-against-accept/vms/avm/block/builder/builder.go#L141)
This PR only removes this check from the mempool verifier.

Why this should be merged
This ensures that the X-chain mempool only contains transactions that are valid to be issued or will be removed from the mempool from transactions that are currently in the processing chain.
How this works
Verifies transactions against the last accepted state rather than the currently preferred state.
