[Reland] Port Chromium OS touch noise filtering to Chromium.

Port Chromium OS touch noise filtering to Chromium. The Chromium OS
touch noise filtering is at
https://chromium.googlesource.com/chromiumos/platform/touch_noise_filter/+/master

When a touch is detected as touch noise, an ET_TOUCH_CANCELLED event is sent and
all of the subsequent events for that touch are dropped. A "touch press"
initiates a new touch.
