[PATCH] Factor out meta-examples

[Jan Kiszka <jan.kiszka@siemens.com>]

From: Jan Kiszka <jan.kiszka@siemens.com>

Move recipes that have exemplary character (currently everything under
recipes-app) into a separate layer that can easily be dropped when
building real images. This also helps to ensure that no assumptions
about customizations and core recipes sharing the same layer sneak in
again.

The meta-isar layer is still not completely clean as we keep
bblayers.conf.sample and local.conf.sample prepared for building example
images.
