As a rule, instead of hard-coding a behavior on specific platforms we
should do dynamic detection.
This commit moves away from always hiding scrollbars on Android and iOS
and instead detects the rendered width of scrollbars in the browser.
Makes it easier to understand what happens when a real element isn't
passed as a target to updateVisibility(). Also makes the code more
robust to future changes.

In the cursor emulation when deciding if the cursor should be hidden -
Instead of checking what's under the cursor, we check the element that
has capture.
This introduced another bug in the cursor emulation. The cursor did not
always disappear properly when using our cursor emulation together with
our setCapture polyfill. More specifically, we saw a problem when a
capture ended on an element without cursor emulation.
We solved this by introducing another visibility check on a timer in
the cursor emulation. However this led to yet another problem where
this timer conflicted with the timer in the setCapture polyfill.
We removed the timeout in the setCapture polyfill and created a
variable to make sure that all the events remaining in the queue can be
completed.

It's not obvious that we want to hide the cursor when we get a leave,
it depends on the element that we're leaving to. This makes the code
more robust.

The names of many variables were too similar. To make the code easier
to follow we renamed:
* _captureElem to _capturedElem
* _captureElemChanged() to _capturedElemChanged()
* captureElem to proxyElem
* elem to target
