[flang] use TBAAForest in TBAABuilder
This is important to ensure that tags end up in the same trees that were created in the FIR TBAA pass. If they are in different trees then everything in one tree will be assumed to MayAlias with everything in the other tree. This leads to poor performance. @vzakhari requested that the old (not-per-function) trees are maintained so I left the old test intact. PR: https://github.com/llvm/llvm-project/pull/68437
