Add AGL reference hardware feature

Add a feature template to enable AGL H3-based reference hardware support. A feature is used as opposed to a new machine in order to meet the requirements that: * the reference hardware be bootable with a h3ulcb machine image to avoid expanding the CI test matrix * the reference hardware support be optional to not hinder Renesas BSP maintenance for the h3ulcb / h3ulcb-kf base machines If the required kernel changes for the reference hardware get upstreamed and eventually become available via the Renesas BSP this can be revisited, as the reference hardware support could then likely be reduced to just building the extra devicetree file(s).
