Single channel alpha formats #9847

It would be useful to have a pixel format for single channel alpha surfaces. These are useful in shaders and are a compact representation of alpha maps.

Running through SDL_Render issues tagged for 3.x, sorry if you get multiple e-mails for this...

We've implemented support for this in our GPU API proposal at #9312, so it should be straightforward to expose to SDL_Render, if this needs to be used beyond SDL_Surface.
