PA: Upgrade DCHECKs to CHECKs in FreeWithSize, guarded by a Finch flag
Upgrade `PA_DCHECKs` to `PA_CHECKs` within `GetSlotStartAndSlotSpan`.
These stricter checks are active when the Finch feature flag (which is
enabled by default) is active, allowing for investigation of potential
inconsistencies in production. When this Finch flag is active, add a
prefetch for slot_span in `FreeWithSizeNoHooks` to potentially mitigate
performance impact from the added `PA_CHECKs`.
