update submodule and patches to QEMU 9.0.0

Biggest change is that AioContext locking got removed, but no changes
required other than dropping the calls to acquire and release it. As a
consequence, the single parameter for the bdrv_graph_wrlock() call got
removed which also required adaptation.

QAPI docs became stricter requiring to document all members.

Other minor changes:

- Single parameter from migration_is_running() was dropped.
- qemu_mutex_(un)lock_iothread() got renamed to bql_(un)lock().
