refactor(render #53): plumb landblockId through WbDrawDispatcher walkScratch

Browse source 
Extends the walk scratch tuple from (entity, meshRefIndex) to
(entity, meshRefIndex, landblockId). The dispatcher's per-entity loop now
has the landblock id available for EntityClassificationCache.Populate's
landblockHint argument (consumed in Task 9). No behavior change.
