[OE-core] [PATCH] image_types: Refactor compression code into a generic compression solution

> The current approach of adding each different compressed image type doesn't

> automatically available using the form <type>.<compression type> in
> IMAGE_FSTYPES. This doesn't change any existing externally visible behaviour
> and the image generation process becomes more efficient as a result too.
