REGRESSION(r202953): Clicking on input[type=file] doesn't open a file…

… picker

Reviewed by Chris Dumez.

The bug was caused by DOMActivate event not propagating out of the user-agent shadow tree
of a file input, and FileInputType not receiving the event to open the file picker.

Made DOMActivate "composed" event which cross shadow boundaries to fix the bug. The feedback
was given back to W3C on WICG/webcomponents#513 (comment)

Added a code to print "OPEN FILE PANEL" in the text when runOpenPanel is called in the UI delegate.

Reviewed by Chris Dumez.

Added a regression test for opening a file picker on a type=file input element.

The test currently only works on WebKit2 since the support for logging "OPEN FILE PANEL"
was only added to WebKitTestRunner.

Also added WebKit2 specific expected results for some tests that tries to open file panel.
