qapi storage-daemon/qapi: Fix documentation section structure

In the QEMU QMP Reference Manual, subsection "Block core (VM
unrelated)" is empty.  Its contents is at the end of subsection
"Background jobs" instead.  That's because qapi/job.json is included
first from qapi/block-core.json, which makes qapi/job.json's
documentation go between qapi/block-core.json's subsection heading and
contents.

In the QEMU Storage Daemon QMP Reference Manual, section "Block
Devices" contains nothing but an empty subsection "Block core (VM
unrelated)".  The latter's contents is at the end section "Socket data
types", along with subsection "Block device exports".  Subsection
"Background jobs" is at the end of section "Cryptography".  All this
is because storage-daemon/qapi/qapi-schema.json includes modules in a
confused order.

Fix both as follows.

Turn subsection "Background jobs" into a section.

Move it before section "Block devices" in the QEMU QMP Reference
Manual, by including qapi/jobs.json right before qapi/block.json.

Reorder include directives in storage-daemon/qapi/qapi-schema.json to
match the order in qapi/qapi-schema.json, so that the QEMU Storage
Daemon QMP Reference Manual's section structure the QEMU QMP Reference
Manual's.

In the QEMU QMP Reference Manual, qapi/cryptodev.json's documentation
is at the end of section "Virtio devices".  That's because it lacks a
section heading, and therefore gets squashed into whatever section
happens to precede it.

Add section heading so it's in section "Cryptography devices".
