Refine Dy2stat APIs to 2.0rc

After discussion, we accepted 3 key points from reviewers:

1. In 2.0rc we changed dygraph_to_static folder to dy2static
2. Keep the three files: convert_call_func.py, convert_operators.py, variable_trans_func.py
3. Remove convert_operators path when users import convert_xxx.

After this PR, users can import convert_xxx APIs by:

import paddle.jit.dy2static.convert_xxx

The file structure will be:

jit
    dy2static
          convert_operators.py
          convert_func_call.py
          variable_trans_func.py
