2fe30bc6 - [AArch64] Add cost model for @experimental.vector.match (#118512)

[AArch64] Add cost model for @experimental.vector.match (#118512) The base cost approximates the expansion code in SelectionDAGBuilder. For the AArch64 cases that don't need generic expansion, fixed-length search vectors have a higher cost than scalable vectors due to the extra instructions to convert the boolean mask.
