kvm tools: arm64: add support for AEM and Foundation models

Browse Source 
The ARMv8 architecture is supported by two publicly available
software models: the Architecture Enveloppe Model, and the
Foundation model.

Both are fairly similar to the Cortex-A57 from a kvm tools point of
view, so we can hijack the A57 implementation to register these
new targets.
