[PATCH] imagetypes_vm: add support for standalone VMDK images

[PATCH] imagetypes_vm: add support for standalone VMDK images

['Clara Kowalsky' via isar-users]

Commit 48c1aee5e797 ("imagetypes_vm: clean up intermediate ova
artifacts") removes the VMDK after assembling the OVA. Some use cases
require only a VMDK, both VMDK and OVA, or only OVA.

With this change, it is possible to set:
- IMAGE_FSTYPES = "vmdk" to generate the VMDK without OVA packaging
- IMAGE_FSTYPES = "vmdk ova.zst" to generate both. In that case, OVA
  depends on the VMDK task and reuses its output without converting the
  disk again
- IMAGE_FSTYPES = "ova.zst" to build just the OVA and clean up the
  intermediate artifacts

This manually models the imagetypes logic. Can't we just make the vmdk
a proper imagetype and let the internal logic defer what is removed and
what is kept?

The current implementation interferes with that.

I'll send a v2 where intermediate image artifacts that have not been 
added to IMAGE_FSTYPES are deleted at the end of do_image, so only the 
wanted image types stay in the deploy dir and no special cleanup is 
needed here in imagetypes_vm.bbclass.
This specific line "+IMAGE_TYPEDEP:ova = 
"${@bb.utils.contains('IMAGE_FSTYPES', 'vmdk', 'vmdk', 'wic', d)}"" is 
needed as for vmdk, OVA depends on the vmdk task and reuses the disk. 
But for Hyper-V's vhdx, OVA keeps its dependency on wic to not build the 
wrong disk format.
