This PR overhauls extension registration in order to make it more
modular.
The `extension` crate now contains an `ExtensionHostProxy` that can be
used to register various proxies that the extension host can use to
interact with the rest of the system.
There are now a number of different proxy traits representing the
various pieces of functionality that can be provided by an extension.
The respective crates that provide this functionality can implement
their corresponding proxy trait in order to register a proxy that the
extension host will use to register the bits of functionality provided
by the extension.

This PR adds a new `/docs` slash command to the Assistant. This slash
command replaces `/rustdoc`.
The `/docs` slash command works with different providers. There is
currently a built-in provider for rustdoc, but new providers can be
defined within extensions. The Gleam extension contains an example of
this.
When you first type `/docs` a completion menu will be shown with the
list of available providers:
https://github.com/zed-industries/zed/assets/1486634/32287000-5855-44d9-a2eb-569596f5abd9
After completing the provider you want to use then you can type the
package name and/or item path to search for the relevant docs:
https://github.com/zed-industries/zed/assets/1486634/6fc55a63-7fcd-42ea-80ce-08c670bf03fc
There are still some rough edges around completions that I would like to
get cleaned up in a future PR. Both of these seem to stem from the fact
that we're using an intermediate completion in the slash command:
1. Accepting a provider completion will show an error until you press
<kbd>Space</kbd> to continue typing.
- We need a way of not submitting a slash command when a completion is
accepted.
2. We currently need to show the provider name in the documentation item
completion list.
- Without it, the provider name gets wiped out when accepting a
completion, causing the slash command to become invalid.
Release Notes:
- N/A
This PR begins the process of making the backing infrastructure for the
`/rustdoc` command more generic such that it can be applied to
additional documentation providers.
In this PR we:
- Rename the `rustdoc` crate to `indexed_docs` as a more general-purpose
name
- Start moving rustdoc-specific functionality into
`indexed_docs::providers::rustdoc`
- Add an `IndexedDocsRegistry` to hold multiple `IndexedDocsStore`s (one
per provider)
We haven't yet removed the rustdoc-specific bits in the `DocsIndexer`.
That will follow soon.

- N/A
