Issue:
[DICT] Add Python support for copy
### Describe the feature
Syntactic and semantic support should be added for `copy`. This should be tested by implementing Python printing

### Test Code
Provide code which does not currently work but which should do when this issue is fixed:
```python
def foo():
    a = {1,1.0, 2:2.0}
    b = a.copy()
    return b
```

Pull request:
Add Python support for dict.copy
Changes made to the files `dict_methods.py`, `class_defs.py`, `test_epyccel_dicts.py`, and `builtin-functions.md` to add Python support for `dict.copy`. Fixes #1881
