Subject: [PATCH] lsp: Send client process ID in LSP initialize request
 (#43988)

Per the [LSP
specification](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#initializeParams),
the client should send its process ID to the language server so the
server can monitor the client process and shut itself down if the client
exits unexpectedly.
