Pranav Bhandarkar 11dad2fa51 [flang][OpenMP] - Add MapInfoOp instances for target private variables when needed (#109862) ...

This PR adds an OpenMP dialect related pass for FIR/HLFIR which creates
`MapInfoOp` instances for certain privatized symbols. For example, if an
allocatable variable is used in a private clause attached to a
`omp.target` op, then the allocatable variable's descriptor will be
needed on the device (e.g. GPU). This descriptor needs to be separately
mapped onto the device. This pass creates the necessary `omp.map.info`
ops for this.
