<!--LLVM PR SUMMARY COMMENT-->

Author: Kareem Ergawy (ergawy)

<summary>Changes</summary>

This PR extends the MLIR representation for `omp.target` ops by adding a `map_idx` to `private` vars. This annotation stores the index of the map info operand corresponding to the private var. If the variable does not have a map operand, the `map_idx` attribute is either not present at all or its value is `-1`.
