Remove PingPong example

The example contains a lot of rather complicated code, which is not
directly related to the demonstrated Bluetooth features.
Remove it in favor of BtChat example, which demonstrates the same
Bluetooth features in a much more compact and understandable way.

Task-number: QTBUG-111972

-    \title Bluetooth QML Ping Pong example
-    \brief A QML example showing Bluetooth communication.
-
-    The Bluetooth QML Ping Pong example presents the socket communication between two
-    Bluetooth devices. The basic concept is the ping pong game where two players
-    communicate via sockets.
-
-    \image qmlpingpong_intro.png
-
-    \include examples-run.qdocinc
-
-    At the beginning, the user selects the role. One device acts as a server and the second
-    one as a client. The server side starts a service named "PingPong server".
-
-    \snippet pingpong/pingpong.cpp Starting the server
-
-    On the client side, the full service discovery on the nearby Bluetooth devices is done.
-
-    \snippet pingpong/pingpong.cpp Searching for the service
-
-    When the ping pong service is discovered, the client connects to the server using the socket.
-
-    \snippet pingpong/pingpong.cpp Connecting the socket
-
-    On the server side, the connected signal is emitted initiating that the client is connected.
-    The necessary signals and slots on the server side are connected.
-
-    \snippet pingpong/pingpong.cpp Initiating server socket
-
-    The game starts after the devices are connected and the screen is adjusted.
-
-    \snippet pingpong/pingpong.cpp Start the game
-
-    The server updates the ball direction and coordinates. The coordinates of pedals are sent
-    to each other every 10ms.
-
-    \snippet pingpong/pingpong.cpp Updating coordinates
-
-    The coordinates are updated and exchanged via sockets. As presented, the server sends its
-    pedal's y coordinate and the ball coordinates whereas, the client sends only its pedal
-    y coordinate.
-
-    \snippet pingpong/pingpong.cpp Checking the boundaries
-
-    In the code above, it was shown how the server checks whether the ball has reached
-    the boundaries of the board. In case of a collision with a pedal, a convex surface
-    is simulated. The part of the velocity normal to the simulated surface is inverted
-    and increased by 10% to speed up the game. In the case of the goal, the server updates
-    the results via its socket.
