3cb9612faa test: add test for Taproot activation (Andrew Poelstra)

cc6b933478 add missing taproot activation params for Liquid v1 (Andrew Poelstra)
bec6bcf31b versionbits: allow specific deployments to override the signalling/threshold values (Andrew Poelstra)
Pull request description:
Sets Taproot to start signalling around noon (California time) on Nov 1, 2021, assuming 95% of blocks are produced between now and then.
Will activate after one week of 100% signalling. If we can pull this off on the first or second try, we will beat Bitcoin which currently looks like it will activate on Nov 16.
**Edit:** actually, even without Speedy Trial, there is one full period (week) where Taproot will be "locked in" but not "active". So it will activate on Nov 15 at the earliest.

Looks like James hardcoded a couple hashes in hard-to-find places, which
caused a unit test to fail. I just changed the hash (which covers UTXO
data which naturally will be different for us on account of our differently
formatted CTxOuts).
TODO: determine how Assumeutxo interacts with the fact that we don't save
out nonces in our normal UTXO serialization. Probably we will need to remove
the nonce from the CCoinStats serialization to avoid having inconsistent
hashes across nodes, since these hashes are now checked in assumeutxo?

Previously we used deployments that would timeout prior to Bitcoin's
invention, which allowed the deployment to still be activated in unit
tests. This switches those deployments to be truly never active.

Pull request description:
Closes#20239 and mitigates my node's problem in #21351.
- Add a few hardcoded seeds for TorV3
- As the [bitcoin-seeder](https://github.com/sipa/bitcoin-seeder) doesn't collect TorV3 addresses yet, I have extracted these from my own node using [a script](https://gist.github.com/laanwj/b3d7b01ef61ce07c2eff0a72a6b90183) and added them manually. This is intended to be a temporary stop gap until 22.0's seeds update.
- Change hardcoded seeds to variable length BIP155 binary format.
- It is stored as a single serialized blob in a byte array, instead of pseudo-IPv6 address slots. This is more flexible and, assuming most of the list is IPv4, more compact.
- Only the (networkID, addr, port) subset (CService). Services and time are construed on the fly as before.
- Change input format for `nodes_*.txt`.
- Drop legacy `0xAABBCCDD` format for IPv4. It is never generated by `makeseeds.py`.
- Stop interpreting lack of port as default port, interpret it as 'no port', to accomodate I2P and other port-less protocols (not handled in this PR). An explicit port is always generated by `makeseeds.py` so in practice this makes no difference right now.
A follow-up to this PR could do the same for I2P.
