Add QWaylandOutput to support multiple outputs

Add a new QWaylandOutput class to support multiple outputs.
Each QWaylandOutput need a window for rendering.

Rename OutputGlobal to Output and Output to OutputResource.

Add support for physical size, mode and available geometry.

Use better defaults for geometry and refreshRate from the QWindow
if available.

A window is no longer passed to QWaylandCompositor constructor
and all output related methods are removed, however one or more
outputs are required for hardware integration.

QWaylandCompositor returns a list of outputs and offers an API to add
or remove outputs.

Hardware integrations can run headless.
