[roll] Roll fuchsia Reland "[starnix][cgroup] Prevent interrupts when a task is frozen"
This is a reland of commit 1b68bc4a02e192e2cab778935af963e15c519c7e
Fix: the underlying zx::Futex from the waiter is subject to spurious
wakeups. Change the no error assert to a loop to ignore spurious
wakeups.
Original change's description:
> [starnix][cgroup] Prevent interrupts when a task is frozen
>
> * Adds `RunState::Frozen` for Cgroup Freezer controlled tasks.
> * Adds `freeze` function in the Waiter to assert the wake is from
> notification instead of any signals, e.g. EINTR.
>
> Ensures frozen tasks remain uninterruptible until thawed.
