Write a function `are_all_dicts_empty` that takes a list of dictionaries as input and returns `True` if all dictionaries in the list are empty, and `False` otherwise.
#### Example Usage:
```python [main.nopy]
print(are_all_dicts_empty([{}, {}, {}])) # Output: True
print(are_all_dicts_empty([{}, {"key": "value"}, {}])) # Output: False
print(are_all_dicts_empty([])) # Output: True
```
#### Requirements:
- The function should handle an empty list as input and return `True`.
- The function should work for any list of dictionaries, regardless of their content.
