Andreas Kling 96ce468b60 LibCore: Add thread-safe weak deferred_invoke() ...

Add a thread-safe deferred_invoke() API on WeakEventLoopReference that
queues work onto the owning thread's event queue and wakes that thread
via EventLoopManager hooks. This avoids calling wake() from foreign
threads during teardown.

Implement current_thread_handle()/wake_thread() in each backend and
track per-thread data so handles are validated before waking:

- Unix: wake via per-thread wake pipe
- Windows: wake via thread wake event
- macOS: wake via stored CFRunLoopRef
- Qt: wake via event target or QEventLoop::wakeUp()
- Android: wake via stored ALooper
