  [mlir][llvmir][OpenMP] Translate affinity clause in task construct to llvmir

Translate affinity entries to LLVMIR by passing affinity information to
createTask (__kmpc_omp_reg_task_with_affinity is created inside PostOutlineCB).

  Implement lowering for omp.iterator in affinity

Create IteratorLoopNestScope for building nested loop for iterator.
Take advantage of RAII so that we can have correct exit for each
level of the loop.

  Log Message:
  -----------
  Refactor and support multiple affinity register for a task

- Support multiple affinity register for a task
- Move iterator loop generate logic to OMPIRBuilder
- Extract iterator loop body convertion logic
- Refactor buildAffinityData by hoisting the creation of affinity_list
- IteratorsOp -> IteratorOp
- Add mlir to llvmir test
