Eliminate cases where we get unused parameter errors only because of a debug assert, and because of short-circuit evaluation not add any overhead into release builds.

Currently channel filter construction returns a `StatusOr<T>`, this change makes it return a `StatusOr<P<T>>` where P is `unique_ptr`, `OrphanablePtr`, `RefCountedPtr`, `DualRefCountedPtr`, etc (most of the code really doesn't need to know, so I'm choosing to leave the flexibility).
That smart pointer is then stored in the channel stack instance, and dereferenced when needed.
This means that channel filters no longer need to be movable (which is a nice simplification), and puts these level-1 filters on a similar memory management track as the level-2 filters we have planned.
(this change also converts client load reporting to v3 apis -- it's a bit accidentally picked up, but seems ok to pull through too)

Make `CallSpineInterface` describe the operations that we need, and return `Promise<>` types -- these are `std::function` wrappers and involve an allocation.
This ought to be acceptable for the use cases we'll be using `CallSpineInterface` for in the short term - and doing this lets us bring the rest of the v3 stack in concurrently with the "v2.5" stack -- the v2 stack using some of the v3 interfaces I put together to unblock chaotic-good.
Later we'll remove this scaffolding and eventually `CallSpineInterface` in its entirety, in preference to something wrapped around `CallFilters`.

To simplify the build process, let's remove unnecessary Bazel bindings. These bindings were originally used to manage differences between OSS and our internal build environment. However, bindings are now deprecated and introduce unnecessary complexity. Removing them will make the build process more straightforward and easier to maintain.

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.

Updates to `CallFilter` to get it ready for integration to `CallSpine`.
This is a bundle commit grabbed from my working branch so there's a few things rolled in here:
* PipeState picks up methods to close it cleanly and in error, and expands its Pull API to signify that error
* Add a `NextMessage` type that encapsulates one message pulled from a pipe (much like `Pipe::NextResult` - except that we know this is a message, and it's built on the `CallFilters` types)
* Add debug stringifiers to many CallFilters types, and better tracing
* Eliminate unused `CallFilters::PipePromise::Pull` type -- other variants are better for all cases
* Add support for filters having the signature `(Handle, Filter*) -> promise returning StatusOr<Handle>` - will support `ClientAuthFilter` in a future commit asynchronously mutating client initial metadata

### NOTE
* We shouldn't merge this PR until GCP cloud functions drops support for Python 3.7 ([Currently scheduled for GCF](https://cloud.google.com/functions/docs/runtime-support#python))
As part of supporting Python 3.12, we're now officially drop support for Python 3.7.
This PR:
* Changed supported Python version from 3.7 to 3.8 in README.
* Replaced distribution test image from `debian:buster` to `debian:bullseye` since the default Python version in buster is 3.7.

When parsing `action` fails we don't touch that memory in the object loader, yet we still call `PostLoad` to fill in any other errors. In that case we are currently relying on undefined behavior to have this test work -- why msan didn't flag it upsets me.
Default `action` to some safe value to avoid the undefined behavior, and log the bad action in the error message to ease debugging here in the future.
