[Python] mix of int and bool disallowed, but mix of int and np.bool_ allowed

### Describe the bug, including details regarding any error messages, version, and platform.

Arrow disallows mixtures of `int` and `bool`:

```python
>>> pa.array([True, 1])
Traceback (most recent call last):
File "", line 1, in
File "pyarrow/array.pxi", line 344, in pyarrow.lib.array
File "pyarrow/array.pxi", line 42, in pyarrow.lib._sequence_to_array
File "pyarrow/error.pxi", line 154, in pyarrow.lib.pyarrow_internal_check_status
File "pyarrow/error.pxi", line 91, in pyarrow.lib.check_status
pyarrow.lib.ArrowInvalid: Could not convert 1 with type int: tried to convert to boolean
>>> pa.array([1, True])
Traceback (most recent call last):
File "", line 1, in
File "pyarrow/array.pxi", line 344, in pyarrow.lib.array

File "pyarrow/error.pxi", line 91, in pyarrow.lib.check_status
pyarrow.lib.ArrowTypeError: Expected integer, got bool
```

but allows mixtures of `int` and `np.bool_`:

```python
>>> pa.array([np.bool_(True), 1])

[
1,
1
]
>>> pa.array([1, np.bool_(True)])

[
1,
1
]
```
