Ryan Ofsky ef29c8b662 assumeutxo: Get rid of faked nTx and nChainTx values 
The `PopulateAndValidateSnapshot` function introduced in
f6e2da5fb7 from #19806 has been setting fake
`nTx` and `nChainTx` values that can show up in RPC results (see #29328) and
make `CBlockIndex` state hard to reason about, because it is difficult to know
whether the values are real or fake.

Revert to previous behavior of setting `nTx` and `nChainTx` to 0 when the
values are unknown, instead of faking them.

This commit fixes at least two assert failures in the (pindex->nChainTx ==
pindex->nTx + prev_chain_tx) check that would happen previously. Tests for
these failures are added separately in the next two commits.

Compatibility note: This change could result in -checkblockindex failures if a
snapshot was loaded by a previous version of Bitcoin Core and not fully
validated, because fake nTx values will have been saved to the block index. It
would be pretty easy to avoid these failures by adding some compatibility code
to `LoadBlockIndex` and changing `nTx` values from 1 to 0 when they are fake
(when `(pindex->nStatus & BLOCK_VALID_MASK) < BLOCK_VALID_TRANSACTIONS`), but a
little simpler not to worry about being compatible in this case.

Test library

This contains files for the test library, which is used by the test binaries (unit tests, benchmarks, fuzzers, gui tests).

Generally, the files in this folder should be well-separated modules. New code should be added to existing modules or (when in doubt) a new module should be created.

The utilities in here are compiled into a library, which does not hold any state. However, the main file setup_common defines the common test setup for all test binaries. The test binaries will handle the global state when they instantiate the BasicTestingSetup (or one of its derived classes).
