  [AArch64] Enable other cost kinds for getCmpSelInstrCost. (#144375)

This removes the CostKind == TCK_RecipThroughput limitation from
getCmpSelInstrCost, allowing it to return more accurate costs for CodeSize and
Lat / SizeLat. Especially for larger vectors under CodeSize, the returned costs
are currently 1, not the legalization cost.
