  [VPlan] Sink retrieving legacy costs to more specific computeCost impls. (#109708)

Make legacy cost retrieval independent of getInstructionForCost by
sinking it to more specific ::computeCost implementation (specifically
VPInterleaveRecipe::computeCost and VPSingleDefRecipe::computeCost).

Inline getInstructionForCost to VPRecipeBase::cost(), as it is now only
used to decide which recipes to skip during cost computation and when to
apply forced costs.
