Acquire the cursor and block index under the same cs_main lock to
eliminate a potential race where a new block could be connected
between capturing the block info and acquiring the cursor, causing
the reported stats to reference a different block than the one
being iterated.

CMake version 4.3 deprecated the imported target `Sqlite::Sqlite3`.
Use the preferred name `Sqlite3::Sqlite3` instead and provide an
alias for older versions of CMake. Also define the same alias when
using vcpkg.

This is less confusing than the verbose=0 alias.

faf71d6 test: [refactor] Use verbosity=0 named arg (MarcoFalke)
99996f6 test: Fix intermittent issue in feature_assumeutxo.py (MarcoFalke)

Pull request description:

  The test has many issues:

  * It fails intermittently, due to the use of `-stopatheight` (#33635)
  * Using `-stopatheight` is expensive, because it requires two restarts, making the test slow

  Fix all issues by using `dumb_sync_blocks` and avoid the two restarts.

  Fixes #33635

f3bf63e kernel: acquire coinstats cursor and block info atomically (w0xlt)
5e77072 rpc: fix race condition in gettxoutsetinfo (w0xlt)

Pull request description:

  Fixes #34263

  A `CHECK_NONFATAL` assertion failure could occur in `gettxoutsetinfo` when a new block was connected between capturing `pindex` and validating it in `GetUTXOStats()`.

  The fix removes the early `pindex` capture since `ComputeUTXOStats()` independently fetches the current best block under lock. The response now uses `stats.hashBlock` and `stats.nHeight` (the actual computed values) instead of the potentially stale `pindex`.
