Promote the plan strategy toggles to be settable per query shape via Persistent Query Settings, following the same recipe as SERVER-129316/129317: migrate any remaining direct global readers to QueryKnobConfiguration (see the needs_replacement burn-down from SERVER-129580), then register/flip pqs_settable: true in the knob IDLs.

Knobs in scope:
* internalQueryDisablePlanCache
* internalQueryDisableLookupExecutionUsingHashJoin
* internalQueryCollectionMaxDataSizeBytesToChooseHashJoin
* internalQueryCollectionMaxNoOfDocumentsToChooseHashJoin
* internalQueryCollectionMaxStorageSizeBytesToChooseHashJoin
* internalQueryDisableSingleFieldExpressExecutor
* internalQueryPlannerUseMultiplannerForSingleSolutions (already knob-registered)
* internalQueryMaxScansToExplode (already knob-registered)
* internalQueryPlannerPushdownFilterToIxscanForSort

Join reorder/method knobs are excluded: they are covered by SERVER-129319.
