[PATCH RFC 16/16] hw/arm: Introduce the microvm machine type

It's a minimalist machine type without PCI nor ACPI support, designed for short-lived guests. microvm also establishes a baseline for benchmarking and optimizing both QEMU and guest operating systems, since it is optimized for both boot time and footprint. Signed-off-by: Xu Yandong --- de
