internal/lsp: propagate and handle context cancellation errors

We don't distinguish between genuine errors and context cancellation in
diagnostics, which often results in superfluous logging of these errors.
Avoid spamming the logs with them by checking.

Also, remove the logic for sending undelivered diagnostics. It's a relic
of old bugs and isn't useful.
