target/arm/machine: remove TARGET_AARCH64 from migration state

Browse source 
This exposes two new subsections for arm: vmstate_sve and vmstate_za.
Those sections have a ".needed" callback, which already allow to skip
them when not needed.

vmstate_sve .needed is checking cpu_isar_feature(aa64_sve, cpu).
vmstate_za .needed is checking ZA flag in cpu->env.svcr.
