Move server-buffer example to manual tests

This is undocumented and demonstrates an experimental feature which
was never maintained or exercised. It's a nice feature, so we keep
the example around for when we get the time to bring it back.

Pick-to: 6.5
Task-number: QTBUG-110993
Change-Id: I045cb2ef02a50017a26226c493607100ea0f1b95

-This example shows how to use the low-level server buffer extension. This
-version of Qt also provides a texture sharing extension that provides more
-functionality and convenience for sharing graphical assets with Qt Quick
-clients: see the texture-sharing example.
-
-Compile up both compositor and client.
-
-If you have the dmabuf-server buffer integration (and you are running Mesa)
-then start the compositor with:
-
-$ QT_WAYLAND_SERVER_BUFFER_INTEGRATION=dmabuf-server ./compositor
-
-
-Note: if you are running a compositor on an X11 desktop, you also need to
-set QT_XCB_GL_INTEGRATION=xcb_egl as usual.
-
-The compositor broadcasts the name of the server buffer integration to
-all clients through the hardware integration extension. Therefore,
-all you need to do is to start the client with
-
-$ ./cpp-client -platform wayland
-
-The client will show all the buffers shared by the compositor.
-
-For testing on desktop, there is also a shared memory based server buffer
-integration that works with any graphics hardware:
-
-$ QT_WAYLAND_SERVER_BUFFER_INTEGRATION=shm-emulation-server QT_XCB_GL_INTEGRATION=xcb_egl ./compositor
-
-Note: the shm-emulation-server integration does not actually share graphics
-buffers, so it will not give any graphics memory savings. It is intended solely
-for testing during development and should never be used in production.
