  Log Message:
  -----------
  [OpenMP][mlir] Support iterator modifier LLVM lowering for map/motion

Lower iterator modifiers on map and motion
(target_data/target_data_begin/target_data_end/target_update) by
building dynamic offload map arrays in OpenMPIRBuilder and populating
them from iterator-expanded map entries during MLIR OpenMP to LLVM IR
translation.

Hoist runtime-sized offload map array allocation for target data with
iterator modifiers so the dynamic count and arrays dominate runtime calls.

This patch is part of feature work for #188061.

Assisted with copilot.
