Allow restricting recipes brought from a layer to a specified list. This
is similar in operation to blacklist.bbclass, but instead specifies a
per-layer whitelist of recipes (matched by BPN) that are able to be
built from the layer - anything else is skipped. This is potentially
useful where you want to bring in a select set of recipes from a larger
layer e.g. meta-oe.
Implements [YOCTO #8150].
