hw/intc/arm_gicv3_common: Move post_load hooks to top-level VMSD

Browse Source 
Contrary to the the impression given in docs/devel/migration.rst,
the migration code does not run the pre_load hook for a
subsection unless the subsection appears on the wire, and so
this is not a place where you can set the default value for
state for the "subsection not present" case. Instead this needs
to be done in a pre_load hook for whatever is the parent VMSD
of the subsection.

We got this wrong in two of the subsection definitions in
the GICv3 migration structs; fix this.
