* Reland x2: Make GetDefaultEventEngine return a shared_ptr
* remove thread leak from NativeDNSResolver
This is not going to work for resolvers that support cancellation.
* give resolvers bounded lifetimes
Some resolver own EventEngines. EventEngines cannot run off the end of
the process since they have unjoined threads (problematic in a small set
of environments). This gives resolvers bounded lifetimes, and allows
replacement of resolvers without ASAN issues of deleting resolvers in
active use (occurs in tests).

* fix windows
* fix surface init test

* use after move
* the test must wait for the callback to be destroyed
* windows fix: delete the resolver on iomgr shutdown, not before
* Make TimerManager threads non-joinable
On gRPC shutdown, any unjoined TimerManager threads will cause TSAN to
detect thread leaks. This fix resolves issues I saw in end2end test
shutdown in another PR, where a single timer manager thread was always
alive after the test ended.
The long-term solution is to integrate the new ThreadPool here, but this
unblocks me for now.
* backport fix
* fix
* shared_ptr<EventEngine> in EventEngine benchmarks
Split off from #30556, this adds the ability to put `std::shared_ptr`s
into ChannelArgs. The EventEngine specialization and preconditioning
will be done separately, when some prework is done there.
* Reland: "Make GetDefaultEventEngine return a shared_ptr (#30280)"
This reverts commit 45959e7cc1.
* Attempted fix with NoDestruct
* Not a process-wide singleton for the type. Just a NonDestruct
* fix
This works around valgrind memory leaks by giving EventEngines a fixed
lifetime. We eventually want ref-counted EventEngines internally, so this is
a step in the right direction as well.
* [WIP] Precondition ChannelArgs with a default EventEngine
This is a step towards using ChannelArgs as the primary means of
accessing EventEngine instances in gRPC-core. If not explicitly provided
by the application, a default EventEngine will populated into
ChannelArgs during preconditioning.
This is not a final state, we may want to enable ref-counting here
instead of using raw pointers. And a refactoring is in order to enable
GetObject instead of the more verbose
GetPointer<EventEngine>(GRPC_ARG_EVENT_ENGINE).
* Refactor ChannelArgs::GetObject to support non-conforming classes
This allows us to not expose `ChannelArgName` in the public interface.
* Add std::shared_ptr to ChannelArgs; Add EventEngine specialization
* subchannel fix; cleanup
* replace GetSharedPtr with overloads of GetObjectRef
* Automated change: Fix sanity tests
* fix the fixer
* fix raw pointer retrieval from stored shared_ptr
* Make GetObjectRef<EventEngine> work (not general to shared_ptr)
* enable shared_ptr ChannelArg support for shared_from_this
* use new EventEngines for tests (not the default global)
* Automated change: Fix sanity tests

* Eliminate post-init in channel stack builder
We've had a post init function on channel stack builder for a very long
time, an it serves to run some code after initialization completes.
We need the functionality for a few things, but the function passed in
is intimately tied to the filter in use - we never vary it between
multiple functions for the same filter... which means it makes more
sense to locate this functionality as part of the filter interface.

Instead of passing transport optionally as an argument adjacent to channel args, pass it as a channel arg directly.
Doing so does not affect semantics, but does allow a cleaner API for channel creation which will become increasingly important as we move towards promises.
