Yijie Ma a7bf07e86a [EventEngine] PosixEventEngine DNS Resolver (#32701 ) This PR implements a c-ares based DNS resolver for EventEngine with the reference from the original [grpc_ares_wrapper.h](../blob/master/src/core/ext/filters/client_channel/resolver/dns/c_ares/grpc_ares_wrapper.h). The PosixEventEngine DNSResolver is implemented on top of that. Tests which use the client channel resolver API ([resolver.h](../blob/master/src/core/lib/resolver/resolver.h#L54)) are ported, namely the [resolver_component_test.cc](../blob/master/test/cpp/naming/resolver_component_test.cc) and the [cancel_ares_query_test.cc](../blob/master/test/cpp/naming/cancel_ares_query_test.cc). The WindowsEventEngine DNSResolver will use the same EventEngine's grpc_ares_wrapper and will be worked on next. The [resolve_address_test.cc](https://github.com/grpc/grpc/blob/master/test/core/iomgr/resolve_address_test.cc) which uses the iomgr [DNSResolver](../blob/master/src/core/lib/iomgr/resolve_address.h#L44) API has been ported to EventEngine's dns_test.cc. That leaves only 2 tests which use iomgr's API, notably the [dns_resolver_cooldown_test.cc](../blob/master/test/core/client_channel/resolvers/dns_resolver_cooldown_test.cc) and the [goaway_server_test.cc](../blob/master/test/core/end2end/goaway_server_test.cc) which probably need to be restructured to use EventEngine DNSResolver (for one thing they override the original grpc_ares_wrapper's free functions). I will try to tackle these in the next step. <!-- If you know who should review your pull request, please assign it to that person, otherwise the pull request would get assigned randomly.

[EventEngine] PosixEventEngine DNS Resolver (#32701 )

This PR implements a c-ares based DNS resolver for EventEngine with the
reference from the original
[grpc_ares_wrapper.h](../blob/master/src/core/ext/filters/client_channel/resolver/dns/c_ares/grpc_ares_wrapper.h).
The PosixEventEngine DNSResolver is implemented on top of that. Tests
which use the client channel resolver API
([resolver.h](../blob/master/src/core/lib/resolver/resolver.h#L54)) are
ported, namely the
[resolver_component_test.cc](../blob/master/test/cpp/naming/resolver_component_test.cc)
and the
[cancel_ares_query_test.cc](../blob/master/test/cpp/naming/cancel_ares_query_test.cc).
The WindowsEventEngine DNSResolver will use the same EventEngine's
grpc_ares_wrapper and will be worked on next.

The
[resolve_address_test.cc](https://github.com/grpc/grpc/blob/master/test/core/iomgr/resolve_address_test.cc)
which uses the iomgr
[DNSResolver](../blob/master/src/core/lib/iomgr/resolve_address.h#L44)
API has been ported to EventEngine's dns_test.cc. That leaves only 2
tests which use iomgr's API, notably the
[dns_resolver_cooldown_test.cc](../blob/master/test/core/client_channel/resolvers/dns_resolver_cooldown_test.cc)
and the
[goaway_server_test.cc](../blob/master/test/core/end2end/goaway_server_test.cc)
which probably need to be restructured to use EventEngine DNSResolver
(for one thing they override the original grpc_ares_wrapper's free
functions). I will try to tackle these in the next step.
