Chengyi Zhao 2e00356c98 lib: core: add prepare_shutdown vfunc to fix Lua GC crash on exit 
When WirePlumber exits, it crashes with SIGABRT. The backtrace shows:

  7  g_closure_invalidate
  10 g_object_unref
  15 g_value_unset
  16 _wplua_gvalue_userdata___gc
  26 close_state (lua_close)
  27 wp_plugin_deactivate
  33 wp_registry_clear
  34 wp_core_dispose

Root cause: lua_State is referenced by both the main plugin and each
WpLuaScript object. During registry cleanup, scripts call lua_close again
on an already-destroyed state, causing use-after-free.

Fix:
- Add a prepare_shutdown vfunc in WpPlugin. Call it from wp_core_dispose
  *before* clearing the registry.
- Lua plugin implements prepare_shutdown to close its lua_State early,
  allowing all __gc finalizers to run while GObjects are still alive.
- Then clear the lua_State pointer from every WpLuaScript object via
  wp_lua_script_clear_lua_state().
- Guard WpLuaScript finalize to skip if pointer is already NULL.

WirePlumber is a modular session / policy manager for
`PipeWire <https://pipewire.org>`_ and a GObject-based high-level library
that wraps PipeWire's API, providing convenience for writing the daemon's
modules as well as external tools for managing PipeWire.

The WirePlumber daemon implements the session & policy management service.
It follows a modular design, having plugins that implement the actual
management functionality.

The WirePlumber Library provides API that allows you to extend the WirePlumber
daemon, to write management or status tools for PipeWire
(apps that don't do actual media streaming) and to write custom session managers
for embedded devices.
