Add row vector and scalar access support to tile operand

* Add the concept of tile view which refers to a specific rectangular
  area of the tile object.
  - The active area is added to TileOperand so that the user can access
    part of the tile.
  - Currently only row vector and scalar access are exposed to the user.
  - All writing operations except load/store op support sub-tile.
* Add tests for sub-tile access.
