[cip-dev][isar-cip-core][PATCH v3 1/4] swupdate-config: move swupdate.cfg from customizations to own recipe

[Quirin Gylstorff <Quirin.Gylstorff@siemens.com>]

From: Quirin Gylstorff <quirin.gylstorff@siemens.com>

This allows downstream customizations without including unwanted
packages.

It also adds the new variable `MACHINE_HW_VERSION` to check the
compatibility between machine/image and the swupdate file.
