* [do not merge] Revamp Service Bindings docs for RPC

- Consolidates Service binding documentation to be within the Runtime APIs section of the docs. Currently docs for configuring a Service binding, and docs for how to write code around Service bindings are in separate sections of the docs, which makes getting started hard, requires jumping back and forth between pages. Relevant content from [the configuration section](https://github.com/cloudflare/cloudflare-docs/blob/production/content/workers/configuration/bindings/about-service-bindings.md) has been moved here, and will be removed.
- Explains what Service bindings are and what to use them for.
- Provides separate code examples RPC and HTTP modes of working with Service bindings.

* Clarify structured clonability.

- Let's not talk about class instances being an exception to structured clone early on. Instead, we can have an aside later down the page. Most people probably wouldn't even expect structured clone to treat classes this way anyway, so telling the about it just to tell them that we don't do that is distracting.

- Adjust the wording in anticipation of the fact that we're likely to add many more types that can be serialized, and this list will likely not keep up. The important thing here is to explain the types that have special behavior (they aren't just data structures treated in the obivous way).

- Briefly describe these special semantics in the list, to get people excited to read more.

* Minor wording clarification.

It was confusing whether "object" here meant a plain object or a class instance.

* Clarify garbage collection discussion.

The language here was not very precise, and would have confused people who have a deep understanding of garbage collectors.

* Better link for V8 explicit resource management.

The previous link pointed to a mailing list thread of messages generated by the bug tracker. Let's link directly to the bug tracker.

* Fix typo.

* Clarify language about disposers.

The language here said that stubs "can be disposed" at the end of a using block, which implies that they might not be, or that this is some sort of hint to the GC. It's more accurate to say that they *will* be disposed, that is, their disposer *will* be called, completely independent of GC.

The advice about when to use `using` was unclear. I've changed the advice to simply say that the return value of any call should be stored into `using`, which is an easy rule to follow.

* Remove "Sessions" section from lifecycle.

This section was placed under "automatic disposal" but doesn't seem to belong here.

I don't think it's really necessary to define a "session" unless we are then going to say something about sessions, but the word doesn't appear anywhere else on the page. Sessions are closely related to execution contexts, but execution contexts were already described earlier.

* Clarify section on automatic disposal.

* Correct docs on promise pipelining.

The previous language incorrectly suggested that promise pipelining would kick in even if the caller awaited each promise. In fact, it is necessary to remove the `await` in order to get the benefits.

* Fix reserved methods doc.

The doc incorrectly stated that `fetch` and `connect` were special on `RpcTarget` in addition to `WorkerEntrypoint` and `DurableObject`. This is not correct.

The doc didn't cover the numerous other reserved method names.

* elide -> omit

* More RPC doc tweaks: Move stuff around! (#13808)

* Move section on proxying stubs to compatible-types.

This isn't really lifecycle-related. But it is another kind of thing that can be sent over RPC.

* Move "promise pipelining" to compatible-types under "class instances".

Promise pipelining isn't really about lifecycle. I think it fits under "class instances" because it is motivated by class instances.

* Merge compatible-types into RPC root doc.

The compatible-types list ends up highlighting the key exciting features of the RPC system. This should be at the root.

* Tweak RPC root page.

I'm removing "How it Works" with the function example because:

1. The example itself doesn't really explain "how it works".
2. We now present this same example down the page under "Functions".

* Add changelog entry

* Update content/workers/runtime-apis/rpc/lifecycle.md
