hw/arm/virt: Get default CPU type at runtime

Prefer MachineClass::get_default_cpu_type() over
MachineClass::default_cpu_type to get CPU type,
evaluating TCG availability at runtime calling
tcg_enabled().

It's worth noting that this is a behavior change:

- Previously only

  ./configure --disable-tcg --enable-kvm
  ./qemu-system-aarch64 -M virt -accel kvm

  would default to 'max' and

  ./configure --enable-tcg --enable-kvm
  ./qemu-system-aarch64 -M virt -accel kvm

  would default to 'cortex-a15'.

- Afterward, -accel kvm will always default to 'max'.
