From: Alex Chapman <alex.chapman@arm.com>

Add `corstone1000-a320-fvp` as a dedicated machine instead of enabling
the Cortex-A320 variant through a kas overlay on `corstone1000-fvp`.

Move the A320-specific machine features, overrides, FVP executable
selection, and Ethos-U85 configuration into the new machine
configuration. Keep the generic `corstone1000-fvp` machine focused on
the base FVP platform.

Update the A320 kas to use `corstone1000-a320-fvp` directly, and
allow pregenerated SSH host keys for the new virtual machine.
