2e2e48f1 - [OpenMP][CIR] Add basic infrastructure for CIR lowering (#171902)

[OpenMP][CIR] Add basic infrastructure for CIR lowering (#171902) This patch adds the basic infrastructure for lowering an OpenMP directive, which should enable someone to take over the OpenMP lowering in the future. It adds the lowering entry points to CIR in the same way as OpenACC. Note that this does nothing with any of the directives, which will happen in a followup patch. No infrastructure for clauses is added either, but that will come in a followup patch as well.
