[RFC PATCH-for-10.1 v6 14/14] hw/arm: Add DEFINE_MACHINE_[ARM_]AARCH64() macros

[Philippe Mathieu-Daudé]

A machine defined with the DEFINE_MACHINE_ARM_AARCH64() macro
will be available on qemu-system-arm and qemu-system-aarch64
binaries.

One defined with DEFINE_MACHINE_AARCH64() will only be available
in the qemu-system-aarch64 binary.
