Michael Barth f2f900bbd5 lsp: Skip serializing of params if unit type (#46027)
Closes #45994 

Per the JSON-RPC specification, `params` "MUST be provided as a
Structured value" or the member "MAY be omitted." See specification
here: https://www.jsonrpc.org/specification#request_object

The code was passing in unit `()` for params which serde_json was
serializing to `null` which is not valid.

This pulls request adds an `is_unit` function and annotates the `params`
fields in the `Request` and `Notification` structs with the following:
 ```rs
#[serde(default, skip_serializing_if = "is_unit")]
```

so that the field will be omitted if the type is unit. This does also introduce a `'static` bound to these structs.

> [!WARNING]
> While this seems to me like a simple change, I am not super familiar with Rust, please look at this PR with extra scrutiny. The last thing I want to do is break everyone's LSP integration.


Release Notes:
- LSP integrations: send language server shutdown requests with correct parameters

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.

Sponsorship

Zed is developed by Zed Industries, Inc., a for-profit company.

If you’d like to financially support the project, you can do so via GitHub Sponsors. Sponsorships go directly to Zed Industries and are used as general company revenue. There are no perks or entitlements associated with sponsorship.
