sled-agent-config-reconciler: Write OS phase 2 images (PR 3/4) (#8540)

With this PR, the config reconciler will actually copy OS phase 2 images
from the TUF repo depot onto the boot partitions of M.2 drives, if
specified to by its `OmicronSledConfig`. It reuses the raw disk writer
from installinator, so _most_ of the new code here is test (or test
support).
