This series introduces image types and conversions as known from OE.
The main motivation is to provide a more flexible way of generating
and processing images, without the need to insert custom tasks (e.g.,
currently we have custom classes adding tasks for things like bz2 or xz
compression of images in several downstream layers).

These patches have been tested on some of our layers, and also
work with some more "challenging" use cases like image-in-image recipes
and custom image types brought by layers.

This only has a bare minimum of conversions (gz, xz), so there should
probably be follow-ups for additional compressions, or things
like checksums, which can also be nicely done with this.

- p1 prepares by removing image-type-suffix from image build directories,
  which enables sharing of the completed rootfs across image types
- p2 refactors the SDK, and makes it an image feature instead of
  a separate recipe (has been discussed here a while ago)
- p3 does the actual work, but keeps all original files
- p4 moves code to different files
- p5 adapts meta-isar
- p6 removes IMAGE_FSTYPES as a dimension in multiconfig. Now that
  we can build multiple types from one rootfs, multconfig is
  just the wrong way of doing this (also been discussed here).
- p7 documents
- p8 adapts start_vm tests

changes since v3:
- better handling of xz compression options (taken from OE)
- fix IMAGE_FSTYPES append in qemuamd64-bullseye.conf
- add patch to adapt start_vm to new image type and file names

changes since v2:
- fix bug where construction of IMAGE_BASETYPES was not recursive
- add comment explaining IMAGE_BASETYPES
- fix ISAR_CROSS_COMPILE exception for ubifs+armhf
- use "IMAGE_CLASSES +=" instead of "INHERIT +=" in machine configs
- fix whitespace errors in documentation

changes since v1:
- rebase
- fixed naming issue in wic.bmap files
- more reasonable default settings for xz
- add documentation to user manual

My understanding is that all downstream layers have to update
IMAGE_FSTYPES (mainly remove "-img"). Isn't that something that should
make it into a changelog? Maybe into the "recipe API changelog"?
