Ladybird: Add common handy actions to context menu

This commit adds the common actions you'd expect to the Ladybird context
menu, arranged like so:

	┌──────────────────────────────┐
	│  Go Back           Alt+Left  │
	│  Go Forward        Alt+Right │
	│  Reload            Ctrl+R    │
	│ ──────────────────────────── │
	│  Copy              Ctrl+C    │
	│  Select All        Ctrl+A    │
	│ ──────────────────────────── │
	│  View Source       Ctrl+U    │
	│  Inspect Element             │
	└──────────────────────────────┘
