qcam: format_convertor: Extend 32 bit ARGB format combinations

Browse source 
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.
