Johan Dahlin 2573aff090 UI/Gtk: Add input events and WebContentView 
Add the web content rendering surface and input handling:
- Events: GDK keyboard, mouse, and scroll event
  translation to Web::KeyEvent/MouseEvent
- WebContentView: ViewImplementation backed by
  GdkMemoryTextureBuilder with incremental update hints,
  enqueue_native_event helpers for mouse/key events
- LadybirdWebView: Custom GtkWidget with focus, key,
  click, motion, and scroll controllers
- Builder.h: Typed GtkBuilder object lookup helper
