This fixes an oversight from the move of nChainTx from the user-supplied
snapshot metadata into the hardcoded assumeutxo chainparams.
Since the nChainTx is now unused in the metadata, it should be removed
in a future commit.

Pull request description:
This picks up the closed pull request #21030 and is the first step toward fixing #21220.
The basic idea is to move all disk access into a separate module with benefits:
* Breaking down the massive files init.cpp and validation.cpp into logical units
* Creating a standalone-module to reduce the mental complexity
* Pave the way to fix validation related circular dependencies
* Pave the way to mock disk access for testing, especially where it is performance critical (like fuzzing)

Code review ACK fadcd3f78e. New organization makes sense, moves extraneous things outside of validation.cpp. PR is also easy to review with helpfully split up moveonly commits.

In #21415 we decided to return `std::optional` rather than `{}` for
uninitialized values. This PR repalces the two remaining usages of `{}`
with `std::nullopt`.
As a side-effect, this also quells the spurious GCC 10.2.x warning that
we've had reported quite a few times. i.e #21318, #21248, #20797.
```bash
txmempool.cpp: In member function ‘CTxMemPool::setEntries CTxMemPool::GetIterSet(const std::set<uint256>&) const’:

787df19b09 validation: don't try to invalidate genesis block (Sebastian Falbesoner)
Pull request description:
In the block invalidation method (`CChainState::InvalidateBlock`), the code for creating the candidate block map assumes that the passed block's previous block (`pindex->pprev`) is available and otherwise segfaults due to null-pointer deference in `CBlockIndexWorkComparator()` (see analysis by practicalswift in #20914), i.e. it doesn't work with the genesis block. Rather than analyzing all possible code paths and implications for this corner case, simply fail early if the genesis block is passed.
Fixes#20914.

1a6323bdbe doc: update developer notes for removal of MakeUnique (fanquake)
3ba2840e7e scripted-diff: remove MakeUnique<T>() (fanquake)
Pull request description:
Since requiring C++17, this is just pointless abstraction. I think we should just "tear the band-aid off" and remove it. Similar to the changes happening in #21366.
Also, having a comment saying this is deprecated doesn't prevent it's usage in new code. i.e : https://github.com/bitcoin/bitcoin/pull/20946#discussion_r561949731.
The repository is fairly quiet at the moment, so any potential complaints about having to rebase should be minimal. Might as well get this over and done with.

25c57d6409 [doc] Add a note about where lock annotations should go. (Amiti Uttarwar)
ad5f01b960 [validation] Move the lock annotation from function definition to declaration (Amiti Uttarwar)
Pull request description:
Based on reviewing #21188
the first commit switches the lock annotations on `CheckInputScripts` to be on the function declaration instead of on the function definition. this ensures that all call sites are checked, not just ones that come after the definition.
the second commit adds a note to the developer-notes section to clarify where the annotations should be applied.

Several other parameters are now redundant since they can be safely
obtained from the chainstate given that ::cs_main is locked. These are
now removed.
