HID: multitouch: add MT_QUIRK_STICKY_FINGERS to MT_CLS_VTL 

Some VTL-class touchpads (e.g. TOPS0102:00 35CC:0104) intermittently
fail to release a finger contact. A previous slot remains logically
active, accompanied by stale BTN_TOOL_DOUBLETAP state, causing
gestures to stay latched and resulting in stuck two-finger
scrolling and false right-clicks.

Apply MT_QUIRK_STICKY_FINGERS to handle the unreleased contact correctly.
