Drain pending requests on language server termination (#4852)
This prevents a freeze while shutting down when using `efm-langserver`.
`efm-langserver` exits immediately after seeing a shutdown request,
without responding to the request. We block awaiting the reply to the
shutdown request which will never come, so we time out.

This change responds to any pending requests with `Err` saying that the
stream has been closed.

Handle language server termination (#4797)
This change handles a language server exiting. This was a UX sore-spot:
if a language server crashed, Helix did not recognize the exit and
continued to send requests to it. All requests would timeout since they
would not receive responses. This would also hold-up Helix closing
itself down since it would try to gracefully shutdown the server which
is implemented in the LSP spec as a request.

We could attempt to automatically restart the language server on crash.
I left this for future work since that change will need to be slightly
complicated: it will need to cover the case of a language server
repeatedly crashing.

embed jsonrpc types from jsonrpc-core crate (#2801)
We should not depend on jsonrpc-core anymore:

* The project just announced it's no longer actively maintained[^1],
  preferring their new implementation in `jsonrpsee`.
* The types are too strict: we would benefit from removing some
  `#[serde(deny_unknown_fields)]` annotations to allow language
  servers that disrespect the spec[^2].
* We don't use much of the project. Just the types out of core.
  These are easy to embed directly into the `helix-lsp` crate.

prevent panic when handling an LSP response with no request (#2475)
A language server may push a response which doesn't belong to any
request. With this change, we discard the response rather than
crashing.

In the case of #2474, the language server sends an error message
with a null request ID which should not ever exist in the
`pending_requests` HashMap.
