The default value of two experiments are set to true because they have already been enabled internally.

The pick_first policy creates a list of subchannels for each resolver update and then iterates over the list, attempting to connect to each subchannel in turn, until one of them succeeds. However, once a subchannel does succeed, the policy unrefs the other subchannels but still retains a bunch of now-unnecessary state in the subchannel list itself. This wastes a bunch of memory, especially now that petiole policies are delegating to pick_first. This PR contains a new pick_first implementation that stops retaining that state, which significantly reduces per-channel memory.
There is one behavior change here, which is that if we have a connected subchannel and we get a resolver update that no longer includes that address, we now go IDLE instead of proactively trying to connect to the new addresses.

It looks like we're settling on moving this functionality into the channel itself - so removing the filter makes sense (especially since it had some significant bugs)

Remove rolled out experiments v3_compression_filter, v3_server_auth_filter; Extend WIP v3_channel_idle_filter for a bit, and extend work_serializer_clears_time_cache until OSS issues with work_serializer_dispatch are resolved.

Disabling before the 1.62 branch cut.
There is a flake in one specific interop test: cloud_to_prod_auth:c++:*:oauth2_auth_token:tls, with * being default or gateway_v4. There is also an unresolved PHP crash on test shutdown, just debug builds on Mac (not Linux or Windows).

The client promise code seems to cause a problem with iomgr pollset shutdown which is causing flakiness.
Right now I don't think it's likely that we'll get this code rolled out before the event engine client lands, so I'm making the experiment dependent on event engine polling.

Add a config to experiments & rollouts to allow dependent experiments to
be flagged.
We're getting past the point where it's possible to reason about which
experiments need to be turned off if we disable some other experiment,
and so this provides some additional rollout safety.
Can be specified in both experiments and rollouts: experiments.yaml
makes the most sense and we should default to it, but rollouts.yaml lets
us put dependencies between internal & external dependencies internally
and that's gonna be a little useful.

Also break the filter stack and promise based versions apart so that I
can re-understand this code.
