I am working on subsequent PRs to update the mapClauseOp and FIR lowering to support declare mapper. The omp.declare_mapper symbol will be used there to identify the mapper.

The omp.declare_mapper operation itself will be used in the OpenMPToLLVMIRTranslation along with OMPIRBuilder to enact the mapping rules defined in it. I have the OMPIRBuilder work up for review already #110001. I will add another patch for OpenMPToLLVMIRTranslation soon. With that we should have all the work in place for supporting OMP Declare Mapper.
