[PATCH v5] image_types.bbclass: get rid of IMAGE_DEPENDS

[Ed Bartosh <ed.bartosh@linux.intel.com>]

The IMAGE_DEPENDS_<type> variables can be set to add dependencies for
individual image types.  Those dependencies are added to the do_rootfs
task, while they really should be added to the specific image type tasks.

These variables are not documented anywhere.

Replaced usage of IMAGE_DEPENDS_<type> with explicitly added
dependencies to do_image_<type> tasks.

[YOCTO #11302]
