What

We ignore the field tx.max_priority_fee_per_gas, as if it were always set to zero.

Why

As a sequenced L2, there is no need to tip the sequencer explicitly. The sequencer is compensated through the base_fee/gas_limit that is paid.

See !11512 (merged) for the full context.

We make max_priority_fee_per_gas to private, and remove all references to it.
