Enable Dropbear SSH in the mass storage OS image, add pregenerated SSH host keys for FVP builds, and document the SSH image build flow in the user guides. SSH support is too large for the flash OS image, so provide a dedicated `core-image-minimal` kas configuration for SSH-enabled mass storage images instead.
