This PR adds **internal** ability to run arbitrary language servers via
WebAssembly extensions. The functionality isn't exposed yet - we're just
landing this in this early state because there have been a lot of
changes to the `LspAdapter` trait, and other language server logic.
## Next steps
* Currently, wasm extensions can only define how to *install* and run a
language server, they can't yet implement the other LSP adapter methods,
such as formatting completion labels and workspace symbols.
* We don't have an automatic way to install or develop these types of
extensions
* We don't have a way to package these types of extensions in our
extensions repo, to make them available via our extensions API.
* The Rust extension API crate, `zed-extension-api` has not yet been
published to crates.io, because we still consider the API a work in
progress.

This practice makes it difficult to locate todo!s in my code when I'm
working. Let's take out the bang if we want to keep doing this.

Follow-up to and fix for #8537.
Turns out that if you set `rules: []` it doesn't mean "no matchers", but
it means "no rules". So let's not set a default here.

This fixes#8533 by allowing users to specify the settings that are
passed to ESLint on workspace initialization.
Example Zed `settings.json` to enable `fixAll` for eslint when
saving/formatting, but only for the `import/order` rule:
```json
{
"languages": {
"JavaScript": {
"code_actions_on_format": {
"source.fixAll.eslint": true
}
}
},
"lsp": {
"eslint": {
"settings": {
"codeActionOnSave": {
"rules": ["import/order"]
}
}
},
}
}
```
The possible settings are described in the README of `vscode-eslint`
here:
https://github.com/Microsoft/vscode-eslint?tab=readme-ov-file#settings-options
- `eslint.codeActionsOnSave.enable` (default: `true`, config key in Zed:
`lsp.eslint.settings.codeActionOnSave.enable`)
- `eslint.codeActionsOnSave.mode` (default: not set by Zed, config key
in Zed: `lsp.eslint.settings.codeActionOnSave.mode`)
- `eslint.codeActionsOnSave.rules` (default: `[]`, config key in Zed:
`lsp.eslint.settings.codeActionOnSave.rules`)
Yes, in the readme it's plural: `codeActionsOnSave`, but since
`eslint-vscode` we're using this old release:
https://github.com/microsoft/vscode-eslint/releases/tag/release%2F2.2.20-Insider
We use the singular version:
https://github.com/microsoft/vscode-eslint/blob/release/2.2.20-Insider/server/src/eslintServer.ts#L461
Our schema looks like this:
```json
{
"lsp": {
"eslint": {
"settings": {
"codeActionOnSave": {
"enable": true,
"rules": ["import/order"],
"mode": "all"
}
}
},
}
}
```
We should probably fix this and upgrade to the newest version of ESLint.
Release Notes:
- Added ability for users to configure settings for ESLint's
`codeActionOnSave`, e.g. specifying `rules` that should be respected
when also using `"code_actions_on_format": {"source.fixAll.eslint":
true}`. These settings can be passed to ESLint as part of the `"lsp"`
part of the Zed settings. Example: `{"lsp": {"eslint": {"settings":
{"codeActionOnSave": { "rules": ["import/order"] }}}}}`

This PR does two things to fix
https://github.com/zed-industries/zed/issues/4325:
1. It changes the way `code_actions_on_format` works to send the
possibly configured code actions to _all_ (and not just the primary)
languages servers. That means configured code actions can now be sent to
ESLint, tailwind, ... and other language servers.
2. It enables `codeActionsOnSave` by default for ESLint. That does
**not** mean that by default we will run something on save, but only
that we enable it for ESLint.
Users can then configure their Zed to run the `eslint` code action on
format. Example, for JavaScript:
```json
{
"languages": {
"JavaScript": {
"code_actions_on_format": {
"source.fixAll.eslint": true
}
},
}
}
```
Release Notes:
- Added ability to run ESLint fixes when formatting a buffer. Code
actions configured in
[`code_actions_on_format`](https://zed.dev/docs/configuring-zed#code-actions-on-format)
are now being sent to _all_ language servers connected to a buffer, not
just the primary one. So if a user now sets `"code_actions_on_format": {
"source.fixAll.eslint": true }` in their Zed settings, the
`source.fixAll.eslint` code action will be sent to ESLint, which is not
a primary language server. Since the formatter (prettier, or external
commands, or another language server, ...) still runs, it's important
that these code actions and the formatter don't clash.

Turns out auto-closing words was a bad idea. win**do**w, **struct**ure,
**sig**n and so on
They don't serve any purpose in `config.toml` nor `brackets.scm` at this
point, so I removed them>
Release Notes:
- N/A
This PR removes the unused crates for plugin support.
We're currently exploring Wasm-based extensions, and it's unlikely that
we'll be reusing any of this existing work.
Release Notes:
- N/A
- Moves languages module from `zed` into a separate crate. That way we
have less of a long pole at the end of compilation.
- Removes moot dependencies on editor/picker. This is totally harmless
and might help in the future if we decide to decouple picker from
editor.
Before:
```
Number of crates that depend on 'picker' but not on 'editor': 1
Total number of crates that depend on 'picker': 13
Total number of crates that depend on 'editor': 30
```
After:
```
Number of crates that depend on 'picker' but not on 'editor': 5
Total number of crates that depend on 'picker': 12
Total number of crates that depend on 'editor': 26
```
The more crates depend on just picker but not editor, the better in that
case.
Release Notes:
- N/A
