[Reland] "[devcoordinator] Limit use of fshost's loader service"

This is a reland of 8e288427c87350b017096cda98e88b95038c0181

Reland reason: Thought to be the cause of GI roller failure
but was confirmed to be a different change.

Original change's description:
> [devcoordinator] Limit use of fshost's loader service
>
> Clarify which things use and rely on the fshost loader service today,
> rather than swapping out devcoordinator's default loader for it and
> having things inherit it through FDIO_SPAWN_DEFAULT_LDSVC.
>
> Bug: 34633
