platform/x86: asus-nb-wmi: Add keymap for display toggle

On the Asus Zenbook 14 (UX3405MA), the Fn+F7 key combination emits
WMI code 0x2d, which was previously unmapped.

Map this code to KEY_DISPLAYTOGGLE. This matches the behavior of the
display toggle/projector mode key found on other Asus laptops, allowing
userspace to handle multi-monitor switching or screen toggling.

Tested on ASUS Zenbook 14 UX3405MA.
