qemu-doc: Belatedly document QMP command arg & result deprecation

A number of deprecated QMP arguments and results were missed in commit
eb22aeca65 "docs: document deprecation policy & deprecated features in
appendix" (v2.10.0):

* Commit b33945cfff "block: Accept device model name for
  blockdev-open/close-tray" (v2.8.0) deprecated blockdev-open-tray,
  blockdev-close-tray argument @device.

* Commit fbe2d8163e "block: Accept device model name for eject"
  (v2.8.0) deprecated eject argument @device.

* Commit 70e2cb3bd7 "block: Accept device model name for
  blockdev-change-medium" (v2.8.0) deprecated blockdev-change-medium
  argument @device.

* Commit 7a9877a026 "block: Accept device model name for
  block_set_io_throttle" (v2.8.0) deprecated block_set_io_throttle
  argument @device.

* Commit c01c214b69 "block: remove all encryption handling APIs"
  (v2.10.0) deprecated query-named-block-nodes result
  @encryption_key_missing and query-block result @inserted member
  @encryption_key_missing.

* Commit c42e8742f5 "block: Use JSON null instead of "" to disable
  backing file" (v2.10.0) deprecated blockdev-add empty string
  argument @backing.

Since then, we missed a few more:

* Commit 3c605f4074 "commit: Add top-node/base-node options" (v3.1.0)
  deprecated block-commit arguments @base and @top.

* Commit 4db6ceb0b5 "block/dirty-bitmap: add recording and busy
  properties" (v4.0.0) deprecated query-named-block-nodes result
  @dirty-bitmaps member @status, not just query-block.

Make up for all that.
