fix(VCalendar): continue touchMove event between days

[yuwu9145]

fix #13174
Also keeps fixing #12366

Description

Cause: @mousemove:time touch target points to v-calendar-daily__day-interval though it is registered on v-calendar-daily__day which is underneath v-calendar-daily__day-interval

Solution: Before it was using elementFromPoint to get the top element under touch point, this fix will use document.elementsFromPoint to extract a list of elements under the touch point, then get the touch hover element based on whose event listener's callback is currently being invoked.
