  [SandboxVec][Scheduler] Don't allow rescheduling of already scheduled (#128050)

This patch implements the check for not allowing re-scheduling of
instructions that have already been scheduled in a scheduling bundle.
Rescheduling should only happen if the instructions were temporarily
scheduled in singleton bundles during a previous call to
`trySchedule()`.
