[Nakamoto] Update pox_3_test.rs to pox4_test.rs

[setzeus]

This issue is meant to mark the kickoff, not completion of the pox4_test.rs that'll be worked in parallel to pox-4.clar. Since pox-4.clar work is still in the early stages, the only confirmed changes worth implementing at the moment revolve around the data structures defined in the design document:

In pox_4_tests.rs what should we use for the epoch and the activation height? In pox_3_tests.rs the latest one is 2.4

StacksEpoch {
    epoch_id: StacksEpochId::Epoch24,
    start_height: EMPTY_SORTITIONS + EPOCH_2_4_HEIGHT,
    end_height: STACKS_EPOCH_MAX,
    block_limit: ExecutionCost::max_value(),
    network_epoch: PEER_VERSION_EPOCH_2_4,
},

// ...

pox_constants.pox_3_activation_height = (EMPTY_SORTITIONS + EPOCH_2_4_HEIGHT + 1) as u32;
pox_constants.pox_4_activation_height = u32::MAX;

@setzeus it turns out there's existing work on this done by @jbencin (see #4106). I reached out to Jeff this morning. Perhaps it makes sense to close this and have just one issue open, so we can have a single place to discuss.

Copy, closing this as a duplicate @moodmosaic
