[Python] pa.array ignores mask parameter when object is an Array

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

```python
>>> import pyarrow as pa

# Bug
>>> pa.array(pa.array([1, 2]), mask=[True, False])

[
1,
2
]

# Expected
>>> pa.array([1, 2], mask=[True, False])

[
null,
2
]

>>> pa.__version__
'15.0.0.dev15116+g9d9cdda'

```

I am working this issue as I am already working on a close one: #39394.
