#### Problem
`chip::Server::Shutdown()` contains
```
chip::Dnssd::ServiceAdvertiser::Instance().Shutdown();
⋮
mCommissioningWindowManager.Cleanup();
```
but the latter restarts `Dnssd::ServiceAdvertiser`.
Instance of project-chip#11880 _Possible use of destroyed pool objects_
#### Change overview
Add `CommissioningWindowManager::Shutdown()` which does not restart DNS.
#### Testing
If `ObjectPool` checks that objects do not outlive it
(originally part of PR project-chip#11698 but deferred due to current leaks),
then `TestCommissionManager` fails without this change.

Problem
We have too many pool allocators.
Previous PRs (#11428, #11487) transitionally use
BitMapObjectPoolwhere previously
System::ObjectPoolhad been used, but this lostthe ability to configure heap allocation.
Change overview
System::Timer(complementing Migrate System::Timer to BitMapObjectPool #11487)Co-authored-by: Zang MingJie [email protected]
Co-authored-by: C Freeman [email protected]
A future PR will use this for Inet pools (complementing #11428);
that is not done here because it would conflict with other Inet
changes under way.
Testing
Added heap versions of unit tests in TestPool. (A future PR will add a
System::Object-style statistics option and re-unify most of these tests.)CI should show
.bssdecreases corresponding to increases in #11487.
