Mel Chen 6d12b3f67d [VP] Refactor VectorBuilder to avoid layering violation. NFC (#99276) ...

This patch refactors the handling of reduction to eliminate layering
violations.

* Introduced `getReductionIntrinsicID` in LoopUtils.h for mapping
recurrence kinds to llvm.vector.reduce.* intrinsic IDs.
* Updated `VectorBuilder::createSimpleTargetReduction` to accept
llvm.vector.reduce.* intrinsic directly.
* New function `VPIntrinsic::getForIntrinsic` for mapping intrinsic ID
to the same functional VP intrinsic ID.
