Subject: [PATCH] drivers/hid: add HID++ support for Logitech MX Anywhere 3S

I've acquired a Logitech MX Anywhere 3S mouse, which supports HID++ over
Bluetooth. Adding its PID 0xb037 to the allowlist enables the additional
features, such as high-resolution scrolling. Tested working across multiple
machines, with a mix of Intel and Mediatek Bluetooth chips.
