<pre>webkitpy: Refactor Device class
https://bugs.webkit.org/show_bug.cgi?id=168332

Reviewed by Alexey Proskuryakov.

Separate the more specific SimulatedDevice from the abstract
idea of a device.

* Scripts/webkitpy/xcode/device.py: Added.
(Device):  Base device class.
(Device.__init__): Initialize _host, name and udid.
(Device.install_app): Function declaration.
(Device.launch_app): Ditto.
(Device.__eq__): Compare two devices by udid.
(Device.__ne__): Ditto.
(Device.__repr__): Return device name and udid in formatted string.
* Scripts/webkitpy/xcode/simulated_device.py: Copied from Tools/Scripts/webkitpy/xcode/simulator.py.
(SimulatedDevice):
(SimulatedDevice.__init__): Call Device.__init__ first.
(SimulatedDevice.delete): Device -&gt; SimulatedDevice.
(SimulatedDevice.reset): Ditto.
(SimulatedDevice.__eq__): Moved to device.py.
(SimulatedDevice.__ne__): Ditto.
(SimulatedDevice.__repr__): Call Device __repr__ first.
(DeviceType): Kept in Scripts/webkitpy/xcode/simulator.py.
(Runtime): Kept in Scripts/webkitpy/xcode/simulator.py.
(Device): Renamed SimulatedDevice.
(Simulator): Kept in Scripts/webkitpy/xcode/simulator.py.
* Scripts/webkitpy/xcode/simulator.py:
(Simulator): Define Simulator.Device class as None.
(Simulator.__init__): Import SimulatedDevice as Simulator.Device.
(Simulator.delete_device): Use Simulator.Device.
(Simulator.reset_device): Ditto.
(Simulator._parse_devices): Ditto.
(Simulator.lookup_or_create_device): Make
(Device): Moved to simulated_device as SimulatedDevice.</pre>
