https://github.com/clementval created https://github.com/llvm/llvm-project/pull/75140

There was some discussion on discourse[1] about allowing call to FIR generation functions from other part of lowering belonging to OpenMP.

This solution exposes a simple `genEval` member function on the `AbstractConverter` so that IR generation for PFT Evaluation objects can be called from lowering outside of the FirConverter but not exposing it.
