mp_image: add imgfmt_name to mp_image_params

Browse Source 
Convenience to override name if imgfmt is not set.

Allows to create mp_image_params without setting imgfmt. Will be useful
for the next change where mp_imgfmt is not available. This is workaround
that will be remved once all codebase switches to pl_fmt.
