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.

I think this makes it less chaotic to edit text when the inlay hints are
on.
It's for cases where you're editing to the right side of an inlay hint.
Example:
```rust
for name in names.iter().map(|item| item.len()) {
println!("{:?}", name);
}
```
We display a `usize` inlay hint right next to `name`.
But as soon as you remove that `.` in `names.iter` your cursor jumps
around because the inlay hint has been removed.
With this change we now have a 700ms debounce before we update the inlay
hints.
VS Code seems to have an even longer debounce, I think somewhere around
~1s.
Release Notes:
- Added debouncing to make it easier to edit text when inlay hints are
enabled and to save rendering of inlay hints when scrolling. Both
debounce durations can be configured with `{"inlay_hints":
{"edit_debounce_ms": 700}}` (default) and `{"inlay_hints":
{"scroll_debounce_ms": 50}}`. Set a value to `0` to turn off the
debouncing.

This PR adds the initial support for loading extensions in Zed.
### Extensions Directory
Extensions are loaded from the extensions directory.
The extensions directory has the following structure:
```
extensions/
installed/
extension-a/
grammars/
languages/
extension-b/
themes/
manifest.json
```
The `manifest.json` file is used internally by Zed to keep track of
which extensions are installed. This file should be maintained
automatically, and shouldn't require any direct interaction with it.
Extensions can provide Tree-sitter grammars, languages, and themes.

Refactor the hint query code to pass along an actual `cx` instead of its
potentially stale, cloned version.
Release Notes:
- Fixed occasional duplicate hints inserted and offset-related panics
when concurrently editing the buffer and querying multiple its ranges
for hints
Based on the great work in
https://github.com/zed-industries/zed/pull/7130 , now sends this data
```
[crates/lsp/src/lsp.rs:588] ClientInfo { name: name.to_string(), version: Some(version.to_string()) } = ClientInfo {
name: "Zed Dev",
version: Some(
"0.122.0",
),
}
```
with every LSP server initialization.
Release Notes:
- Added Zed name and version to LSP InitializeParams requests
Adding the typos crate to our CI will take some doing, as we have
several tests which rely on typos in various ways (e.g. checking state
as the user types), but I thought I'd take a first stab at fixing what
it finds.
Release Notes:
- N/A
This way, only the visible part gets frequently queried on typing (and
hint /refresh requests that follow), with queries for invisible ranges
cancelled eagerly.
