meta-agl-bsp: Add reference hardware GPS support
Add recipe for gpsd configuration for the reference hardware, which also installs a script plus systemd unit drop-in to handle enabling and disabling it. The latter is required due to the reference hardware's reuse of the h3ulcb image, which means the existing PREFERRED_PROVIDER_virtual/gpsd-conf scheme is not sufficient in this case.
