fix apache/echarts#13958

Why this bug happens:

This bug is brought when fixing the wrong mouseout event triggered in SVG renderer in https://github.com/ecomfe/zrender/compare/fix-global-out?expand=1#diff-619a90e06ad2f3966dac739e2d1fb17006d9f44978316c758d694a40cde28201L222

But in canvas renderer, the event.target will is the canvas element when mouseout. Not the viewport. So the globalout will never be triggered.

Fix:

Determine if the target element is a descendant of the viewport. If so, both mouseout and globalout event won't be triggered.
