block/qapi: Human-readable ImageInfoSpecific dump

Browse source 
Add a function for generically dumping the ImageInfoSpecific information
in a human-readable format to block/qapi.c.

Use this function in bdrv_image_info_dump and qemu-io-cmds.c:info_f to
allow qemu-img info resp. qemu-io -c info to print that format specific
information.
