Draft: perf(qemu): qemu emulator kvm optimisation
using the -accel kvm and then attempting OS specific accelerators
before falling back onto the default -accel tcg, which
gives a performance increase when those accelerators are available for
their respective platforms such as in cases where the cpu
arch for the host and guest match.
The accelerators that have been chosen were based on the table in the QEMU accelerator docs:
https://www.qemu.org/docs/master/system/introduction.html#virtualisation-accelerators
relates to #6, #12 (closed)
