ci: Clone cached Zephyr repository with shared objects

Browse source 
In the new ephemeral Zephyr runners, the cached repository files are
located in a foreign file system and Git clone operation cannot create
hard-links to the cached repository objects, which forces the Git clone
operation to copy the objects from the cache file system to the runner
container file system.

This commit updates the CI workflows to instead perform a "shared
clone" of the cached repository, which allows the cloned repository to
utilise the object database of the cached repository.

While "shared clone" can be often dangerous because the source
repository objects can be deleted, in this case, the source repository
(i.e. cached repository) is mounted as read-only and immutable.
