While libcamera uses meson as its build infrastructure, applications are
free to use other make systems. CMake is widely used, so add an example
CMakeLists.txt to support building simple-cam and linking against
libcamera using cmake.

The completed Request can contain extra data associated with the
completed capture to report IPA state or properties of the capture to
the application.
Process and report any metadata that is associated with the request
when it completes, to demonstrate the extra metadata available to be
processed.
Now that there is substantially more information than one line per
completed request, start each completed Request with a blank line to
separate from previous completions and report the state of the Request
itself with its .toString() helper.

Commit 14529b6d1c4a ("simple-cam: Early return if no cameras are found
on the system") added a check to ensure that at least one camera is
present in the system to avoid a crash otherwise. The check was however
placed towards the end of the main() function, way after the camera is
accessed, possibly due to a rebase conflict. Move it before accessing
the first camera.
While at it, replace usage of std::vector::size() with
std::vector::empty() which expresses the intent better.

In libcamera commit 32635054bc76 ("libcamera: framebuffer: Prevent
modifying the number of metadata planes"), the planes are returned as a
const span rather than a vector from the metadata.
This provides better protection on the underlying structures, but was a
break in the API.
Update simple-cam to use the new API.

The CameraManager should be released when it is no longer used. A
unique_ptr will handle this automatically, and convey the lifetime of
the object.
Update simple-cam to show that managing the lifetime of the
CameraManager is recommended practice.

libcamera moved its EventDispatcher and Timer API to its internal API,
since providing an event loop to applications should not be the job of
libcamera. Application utility like cam, were ported to use libevent,
hence inspired from that, un-break simple-cam by using the similar
implementation to replace the EventDispatcher and Timer functionality
by libevent.

It is important to delete the created allocator, otherwise
it holds on to references of the media-device, and complains at shutdown.
Clean up neatly by deleting the object before after the stream resources
are free. That could potentially all be done by the destructor anyway.
