cache_components: Add the ability to cache the shim-v2

In order to cache the shim-v2 we're considering the the cached component
can be used if:
* There were no changes in the runtime directory
* There were no changes in the golang version used
* There were no changes in the rust version used
  * We don't build the rust agent, but better be prepared for the future
* There were no changes in the following files that are provided by the
  rootfs builds:
  * root_hash_vanilla.txt
  * root_hash_tdx.txt
