examples: Add imageformats example (#2872)
* examples: Add imageformats example

Example which renders RGBA color wheel, alpha gradient and full value channel textures to
catch conversion errors and bad internal type representations between different backend
renderers.

The example uses bimg to convert from a master texture to different textures.

Each texture is rendered in an ImGui list using `ImGui::Image`. A close-up is visible
when hovering over each image.

U and I textures are skipped because they don't work for sampling.
Compressed textures are skipped because they don't have conversion functions.
Depth textures are not rendered because they don't work with channels.

* pixelformats: Present texture format in table

* Update pixelformats.cpp

* Update pixelformats.cpp

* pixelformats: Update screenshot

* pixelformats: Add checkerboard background
