arm-autonomy: Create arm64-autonomy-guest machine

Browse Source 
Create a minimalistic BSP to be used as an arm-autonomy-guest on ARM64.
The BSP is enabling ARM64 and SMP in the kernel configuration and is
enabling the arm-autonomy-guest in DISTRO_FEATURES.
Rework README.md file.

This layer is adding the following machines:
* arm64-autonomy-guest: this machines creates a minimal BSP suitable to be used
as an autonomy guest. It is in fact only activating ARM64 architecture and
SMP in the linux kernel and is enabling the DISTRO_FEATURE
arm-autonomy-guest.
