Fix compilation errors in ReshapeOpCreate refactoring

- Remove .getResult() call on Value at line 1047
- Cast Value to RankedTensorType before getShape() at line 6105
- Remove unused variable post_reshape at line 21655
- Call getDefiningOp() on Value before setShardings at lines 22797, 22809, 23237
- Remove unused variables newLhsType, newRhsType at lines 31319-31322
- Remove unused variable newInputTy at line 31431
