efc0ab0f - [AArch64][CostModel] Add SVE bfloat arithmetic tests (NFC) (#166951)

[AArch64][CostModel] Add SVE bfloat arithmetic tests (NFC) (#166951) This patch adds cost model tests for `bfloat` operations with `+sve-b16b16`. Currently, some of these costs are higher than they should be as the cost model is assuming `bfloat`s need promotion, but some of these operations are natively supported with `+sve-b16b16`.
