Andreas Kling 24afab20cc LibWebView: Defer process cleanup to avoid signal handler deadlock ...

When a child process exits, the SIGCHLD handler was destroying the
Process object synchronously within the signal dispatch context. This
triggered Process::~Process() which called m_connection->shutdown(),
attempting to join the IPC IO thread.

Joining threads from within signal handler context can cause deadlocks,
as observed when WebContent crashes during test-web runs.

Fix this by deferring the on_process_exited callback using
Core::deferred_invoke(), ensuring the Process destruction happens in
normal event loop context.
