[PATCH 1/1] replace custom OVA logic with imagetype logic

[Felix Moessbauer <felix.moessbauer@siemens.com>]

This patch refactors the imagetypes_vm class for virtualbox and vmware
images. The existing manual implementation does not work anymore when
referencing ova config files across layers. Instead, we now use the
imagetypes logic, which avoids the problematic changes of
FILESEXTRAPATHS and SRC_URI.

+### VM Image
+
+As a result of the Bitbake 2.0 migration, the vm image type has to be reworked:
+Previously, a path to the `OVF_TEMPLATE_FILE` had to be somehow injected so
+that the description file was located. This is now replaced by the imagetype
+logic. By that, the `OVF_TEMPLATE_FILE` needs to be located in a directory
+named according to the machine, next to the image file. If this is not possible
+(e.g. in cross-layer scenarios), add the location to the FILESEXTRAPATHS of the
+corresponding machine.conf.
