Improve warning message for invalid desktop VRAM compression settings

- Display the source file path.
- Display the valid compression algorithms on desktop platforms.
- Use "desktop platforms" instead of "PC" to avoid ambiguity.
- Use "may" instead of "will", as desktop platforms can still sometimes
  display ETC1/ETC2 textures depending on the GPU and drivers.
