Attempt 2 at enabling a tab dragging test

Attempt 2 at enabling a tab dragging test

This was reverted because of flake on linux. I've identified why the
flake was happening and filed a bug, so I'm leaving the enabling as
only chromeos and windows at this time.

These tests were disabled because the resize lock can trigger at
random points, blocking event delivery and breaking the tests. I've
added a switch to disable the resize lock so that events now have
known delivery order.
