Kareem Ergawy 2918a47f42 [mlir][OpenMP] Annotate private vars with map_idx when needed (#116770) ...

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`.

This makes matching the private variable to its map info op easier (see
https://github.com/llvm/llvm-project/pull/116576 for usage).
