Subject: [PATCH] runtime-rs: support measured rootfs within Makefile

In CoCo scenarios, measured rootfs is very important for the whole
system's measurement. As the infrastructure (packaging, root hash
generation, etc.)has been setup, we need add related items in
configurations or knobs in Makefile

Fixes #11502
