Update Dynamic Fee Calculation to Be "Chunk-Builder Safe"

[patrick-ogrady]

To ensure that chunk producers only include transactions that will pay fees, chunk producers need to be able to compute the max fee that any transaction they include may be required to pay.

If we use our existing fee mechanism, this fee could be far far higher than the fee when the chunk is being built. We may want to make the fee change less dynamic (changing once per epoch) or make it fixed (only changed via "governance").
