[OE-core] [RFC PATCH 1/1] package.bbclass, task.bbclass: Allow doc-pkgs in EXTRA_IMAGE_FEATURES

[Jason Wessel]

The doc-pkgs package group is defined, but some of the "plumbing" is
missing to allow it to work like the dbg-pkgs and dev-pkgs.  This
patch adds the "plumbing" to allow you to specify doc-pkgs to install
all the documentation packages that correspond to the other installed
packages on the target file system in a similar manner to the dbg-pkgs.

[Yocto #2614]
