Tooltip popover screen edge avoidance

[arkwright]

Tooltip popovers (EuiIconTip shown) can extend past the edge of the screen in some scenarios. Ideally the tooltip would dynamically adjust its position to avoid rendering content off screen.

@arkwright it should do this based on https://github.com/elastic/eui/blob/master/src/services/popover/popover_calculate_position.js. If you can provide it, I'd love to see what scenario replicates this.

I have seen instances where the listening is a little laggy though.

As it turns out, this is reproducible in both FF and Chrome on the tooltip documentation page. I just resized my window to mobile dimensions.

@cjcenizal do you mind checking this out? I see that it's working for EuiToolTip but not these EuiIconTip ones. Haven't peeped the code very closely.
