[PATCH v5 1/8] migration/vmstate: export vmstate_{load, save}_field helpers

[Alexander Mikhalitsyn <alexander@mihalicyn.com>]

From: Alexander Mikhalitsyn <aleksandr.mikhalitsyn@futurfusion.io>

Let's export vmstate_{load,save}_field() helpers, they will
be used in next patches to support fully-dynamic arrays with NULLs.
