PixelFormat was previously an alias for unsigned int but is now a
class. Make all functions taking PixelFormat do so as a const reference.

Instead of having to include linux/drm_fourcc.h everywhere a DRM FourCC
is used in conjunction with PixelFormat include the header directly in
pixelformats.h.

Use the PixelFormat instead of unsigned int where a pixel format is to
be used. PixelFormat is defined as an unsigned int but is about to be
turned into a class to add functionality.
There is no functional change in this patch.

Add further support to the pixel format convertor to allow ARGB, RGBA,
and ABGR formats to be displayed in qcam.
Blank lines are added between the sections for NV, RGB, YUV, and MJPEG
configurations.
The implementation of the RGB conversions are highly inefficient, and
where possible should be extended to use hardware accelerations such as
OpenGL, or in the event that the input format is identical (or
compatible) with the output format - a more optimised memcpy should be
implemented.

It is not sustainable to add a new flag for every new video format
family (eg. YUYV, RGB, NV, MJPEG, etc), so add a formatFamily enum to
indicate these in the FormatConverter.
Note that formats are grouped into families based on if they are able to
share a set of parameters for conversion.

qcam is a sample camera GUI application based on Qt. It demonstrates
integration of the Qt event loop with libcamera.
The application lets the user select a camera through the GUI, and then
captures a single stream from the camera and displays it in a window.
Only streams in YUYV formats are supported for now.
