Summary:
Extends the output device and output configuration interfaces with the
ability
to query and set the RGB color intensity curves (gamma ramps) of the
associated output.
Test Plan: Manually. Auto tests will be added to this diff soon.

Summary:
In order to have fractional scaling in kwin, we need to communicate it with
kscreen, which means changing the data type in our config protocols.
This introduces a new method on outputdevice and outputconfiguration
to set/request scale as a float.
wl_output is and should remain unchanged as an int
No urgent rush for reviewing/merging this as it's useless without other changes.
Test Plan: Attached unit tests

This implements the server part of the screen management protocol. The
protocol is implemented as a wayland protocol.
It provides the following mechanisms:
- a list of outputs, close to wl_output, with additional properties for
enabled, uuid, edid, etc.. These OutputDevices correspond to a
connected output that can be enabled by the compositor, but is not
necessarily currently used for rendering.
- a global OutputManagement, which allows creating config objects, one
per client. The client can make changes to the outputs through
setScale(outputdevice*, scale) for example.
- an OutputConfiguration resource, that can be handed to a client and
used for configuration. Changes are double buffered here. Only after
OutputConfiguration.apply() has been called, the changes are relayed
over the global OutputManagement.
The compositor is responsible to handle changes.
For a more detailed description, see the API docs in especially
outputconfiguration.h.
