  video: Add SDL_PremultiplySurfaceAlphaToARGB8888()
  
  A number of video backends need to get ARGB8888 formatted surfaces with
  premultiplied alpha, typically for mouse cursors. Add a new function to
  do this, based loosely on legacy_alpha_premultiply_ARGB8888() from the
  KMSDRM backend.
  
  The new function, SDL_PremultiplySurfaceAlphaToARGB8888() takes two
  arguments:
  - src: an SDL_Surface to be converted.
  - dst: a buffer which is filled with premultiplied ARGB8888 data of the
    same size as the surface (assuming pitch = w).
  
  This is not heavily optimised: it just repeatedly calls SDL_GetRGBA() to
  do the conversion, but should do for now.
