After #40732 it became possible that getrusage() (from detachQuery(),
from buildPushingToViewsChain()) will be called for incorrect thread,
and so when the difference will be calculated it will be simply garbage.
But actually the root of this problem is #25714, after which it became
possible to have multiple ThreadStatus for one thread, and this is very
tricky (sigh).
Here are some other thoughts about it:
- Make ThreadStatus nested - decided that complexity does not worth it,
at least only for this case
- Move some members into ThreadGroupStatus - will break per-thread
statistics (and hence query_thread_log, BTW does somebody uses it?)
- Move some members into a separate structure
But decided to fix the issue w/o any refactoring, to make easy for
backport.

- lots of static_cast
- add safe_cast
- types adjustments
- config
- IStorage::read/watch
- ...
- some TODO's (to convert types in future)
P.S. That was quite a journey...
v2: fixes after rebase
v3: fix conflicts after #42308 merged
