HID: magicmouse: Apple Magic Trackpad 2 USB-C driver support

Browse Source 
[ Upstream commit 87a2f10395c82c2b4687bb8611a6c5663a12f9e7 ]

Adds driver support for the USB-C model of Apple's Magic Trackpad 2.

The 2024 USB-C model is compatible with the existing Magic Trackpad 2
driver but has a different hardware ID.
