[PATCH v3 09/23] monitor: Include missing 'qemu/coroutine-core.h' header

"monitor/monitor.h" declares monitor_set_cur() which use the
'Coroutine' type, itself declared in "qemu/coroutine-core.h".
Include the latter to avoid when refactoring unrelated headers:

  In file included from ../../target/sh4/monitor.c:26:
  qemu/include/monitor/monitor.h:32:26: error: unknown type name 'Coroutine'
     32 | Monitor *monitor_set_cur(Coroutine *co, Monitor *mon);
        |                          ^

Fixes: e69ee454b5f ("monitor: Make current monitor a per-coroutine property")
