BUG: inconsistent creation of IntegerArray from boolean values
When creating a nullable integer array from boolean values, we are being inconsistent between a boolean numpy array and a object array with bools:

```python
>>> pd.array(np.array([True, False]), dtype="Int64")  
<IntegerArray>
[1, 0]
Length: 2, dtype: Int64

>>> pd.array(np.array([True, False], dtype=object), dtype="Int64")  
---------------------------------------------------------------------------

----> 1 pd.array(np.array([True, False], dtype=object), dtype="Int64")
