[LoopVectorize] Clear cache of `LoopAccessInfoManager`

LAI is cached during the LoopDistribute pass, and is later re-used during LoopVectorize. The problem is that LoopVectorize changes SCEV, and the cached LAI does not get updated. Hence, when re-using the cached LAI, it references an invalid SCEV.

Fixes #59319
