[flang][hlfir] lower hlfir.product into fir runtime call
The shared code for lowering the sum and product operations in flang/lib/Optimizer/HLFIR/Transforms/LowerHLFIRIntrinsics.cpp have been moved into a new class HlfirReductionIntrinsicConverion. Depends on: D148719 Differential Revision: https://reviews.llvm.org/D149644
