platform/x86: intel-hid: Enable 5-button array on ThinkPad X1 Fold 16 Gen 1

Browse source 
The Lenovo ThinkPad X1 Fold 16 Gen 1 has physical volume up/down
buttons that are handled through the intel-hid 5-button array
interface. The firmware does not advertise 5-button array support via
HEBC, so the driver relies on a DMI allowlist to enable it.

Add the ThinkPad X1 Fold 16 Gen 1 to the button_array_table so the
volume buttons work out of the box.
