Applied IWYU recommendations (mostly). I deviated on libraries, it always wanted me to include the inner headers for SDL, ffmpeg, etc. but the definitions were normally expected to be exported by a top level header. wxWidgets was particularly problematic since it wanted me to use the gtk specific includes instead of the generic ones. I do not intend to add include-what-you-use to the CI/CD pipelines at this time but some pragmas were added to the code to make it report somewhat cleaner.
