santorac 849a8da4d9 Added unit tests for PngFile. 
Fixed a couple issue like palettized files would not load, and stripping alpha was not affecting the color type reported by libpng. Also cleaned up some error reporting.
Added AzFramework to Atom/Utils tests to support PngFile testing.

santorac 7a8eb8eda5 Added a new PngImage utility class that wraps libpng. This replaces the use of OpenImageIO in O3DE (although OpenImageIO is still a build dependency for now).
