HID: quirks: Add HID_QUIRK_IGNORE_MOUSE quirk

Browse Source 
Some USB HID mice have drivers both in HID as well as a separate USB
driver. The already existing hid_mouse_ignore_list in hid-quirks manages
this, but is not yet configurable by usbhid.quirks, unlike all others like
hid_ignore_list. Thus in some HID devices, where the vendor provides USB
drivers only for the mouse and lets keyboard handled by the generic hid
drivers, presence of such a quirk prevents the user from compiling hid core
again to add the device to the table.
