browser(webkit): let web page close when it has open context menu (#2802)

Browse source 
Review URL: 42f86e9d77

Currently, if web page has an open context menu, then it won't close.
This prevents browser from quitting.

In stock safari, this behavior can also be observed in a way that
context menu will stay opened even if related page got closed.

While investigating this behavior on Mac, a crucial observation was
that `[NSMenu popUpContextMenu]` is spawning a nested event loop,
keeping reference to `WebContextMenuProxyMac` instance, which in turn
keeps references on associated `NSView` with `WKWebView`.

To exit the loop, we need to explicitly cancel context menu. For this,
this patch adds a method `hide` on `WebContextMenuProxy` that uses
port-specific code to cancel context menu.

Windows part of this patch is somewhat speculative: I didn't check
it, but given the same symptomps, I applied the same solution.

Fixes #2700
