platform/x86: thinkpad_acpi: handle HKEY 0x1402 event

2025 Thinkpads F11 key launch the Intel Unison app on Windows,
which does some sort of smart sharing between laptop and phone.

Map this key event to KEY_LINK_PHONE as the closest thing we have.
This prevents an error message being displayed on key press.
