Add a savevm handler for a module to opt-in sending extra sections right
before postcopy starts, and before VM is stopped.
RAM will start to use this new savevm handler in the next patch to do flush
and sync for multifd pages.
Note that we choose to do it before VM stopped because the current only
potential user is not sensitive to VM status, so doing it before VM is
stopped is preferred to enlarge any postcopy downtime.
It is still a bit unfortunate that we need to introduce such a new savevm
handler just for the only use case, however it's so far the cleanest.
