Imported from GitHub PR https://github.com/tensorflow/tensorflow/pull/49970

1, add hlo-to-lhlo support for DynamicReshape and DynamicBroadcastInDim

2, add a flag `convert-to-lmhlo-only` to seperate following two case:
   - hlo-to-lhlo only. Simply lowers all mhlo ops to their lmhlo
     counterparts, do not apply any optimization (e.g. elide any
     buffer copy). Buffer optimization is not easy in dynamic
     shape world especially when involving control flow, thus we
     leave this to another dedicated pass.

   - hlo-to-lhlo-or-memref-directly. Lowers some metadata-only mhlo
     ops (e.g. reshape) to memref dialect directly and Lowers others
     to their lmhlo counterparts.
