packagegroup-agl-core-boot: add package distro-build-manifest

The purpose of distro-build-manifest is to generate and distribute build
manifests for a given AGL build (generally, an image build).

The recipe generates the build manifest 'platform-build-info' at each build
(no caching) and this manifest is then stored in 3 locations with different set
of data:
 * image: in /etc/platform-build-info
 * deploy dir: image/$MACHINE/platform-build-info
 * sdk: generated but not packaged yet

Important Note: the 3 manifests contain at least the 'target manifest' but some
extra information are added depending on the target location:
* build host information are only available in the deploy dir manifest
* SDK specific data are only available in the SDK manifest

An example of generated build manifests (sorry for long lines):
