[Tizen] Add ChipMdnsShutdown()

[hyunuktak]

Problem

Issue #8001 MdnsAvahi destructor segfault; require separate shutdown

MdnsAvahi can cause a crash on exit due to a static instance running
code in its destructor after dependent components have shut down.

Change overview

• Add ChipMdnsShutdown(). This is a narrow fix, which does not attempt
  to address other potential problems with singleton mDNS state.
