OS X: Forward key events to popup window if present

Browse Source 
On OS X we don't treat popup windows as worthy of being activated and
focus windows (key windows). Instead we keep track of the active popup
windows and forward events to them manually.

The forwarding logic is split between QPA, which handles mouse, and
QWidgetWindow and QQuickWindowPrivate, which handles key events.

This commit adds the logic for key events to QPA, which is the right
platform layer for this kind of workarounds. The widget code is left
as is for now, and the QQuickWindowPrivate code can be removed in
a follow up.
