Revert "[PartitionAlloc] Don't sort already-sorted freelists."

This reverts commit e594ceb5413566356e46fb1793383fc34f46a6ba.

Reason for revert: Newly introduced test failing on some configs.

Original change's description:
> [PartitionAlloc] Don't sort already-sorted freelists.
>
> If a slot span hasn't been touched since the last sort, there is no need
> to sort it again. This is intended to reduce the CPU cost of freelist
> sorting.
>
> This is motivated by stack-sampled metrics showing that the cost of
> freelist sorting is non-trivial in the browser process. It also allows
> to track whether a slot span is "idle", which may be used to decommit
> part of the freelist if possible.
