Use AddressResolve in CASE (#15934)

* Squash merge: use address resolve for case

* Add dependencies to compile on darwin (using xcode)

* Updates for ESP32 compile: ensure the address resolve impl header is defined everywhere

* Working through fixing Cirque.

Fixes:
  - add proper CloseSession instead of a 'establish then close' since
    address resolve is not instant anymore
  - added retries and timeouts during the resolve test (since resolve
    may take a while)
  - Made GetPeerAddress to NOT rely exclusively on the dns cache and
    added a TODO to fix it
  - removed noisy logging for node resolution (address resolver also
    logs)
  - added extra logging to figure out what we connect to during CASE
    session establishment.

Still not fully passing, but progress

* Restyle

* Fix compile, address code review comments

* Add back node id resolve logging on progress

* Add comment that CloseSession is TEMPORARY

* Restyle

* Fix double-free during CASE session cleanup (cleanup methods do case cleanup)

* Add ordering issue on freeing commissionee to fix use after free error

* Update comment: I did test both negative test cases under valgrind

* Apply suggestions from code review

* Apply suggestions from code review

* Fix potential use-after-free issue in OperationalDeviceProxy::HandleCASEConnected.
