In commit abc24d86cc0364f we accidentally broke migration of
the stack pointer value for the mode (process, handler) the CPU
is not currently running as. (The commit correctly removed the
no-longer-used v7m.current_sp flag from the VMState but also
deleted the still very much in use v7m.other_sp SP value field.)
Add a subsection to migrate it again. (We don't need to care
about trying to retain compatibility with pre-abc24d86cc0364f
versions of QEMU, because that commit bumped the version_id
and we've since bumped it again a couple of times.)
