fix: update touch position on touchmove event

[guersam]

Closes #3065

My screencast recorder doesn't show the pointer even if I turned on the setting, but you'll get the idea.

before:
Screencast from 2022년 07월 25일 21시 28분 56초.webm

after:
Screencast from 2022년 07월 25일 21시 27분 05초.webm

this commit seems to be the cause of #3065.

Before this change, there was only active event reference that is updated along mousemove and touchmove events. This commit separate active and touch, but unlike active, touch is no more updated when handling touchmove event.

Upon reading the history, I think this PR should be enough to fix #3065.

Just found out it's working only with the canvas renderer. Need to work on svg renderer.
