URL: https://github.com/apache/arrow/issues/54641
### Describe the bug, including details regarding any error messages,
version, and platform.
On Windows, timestamp parsing with a `strptime` format fails when the format
contains `%a`, `%A`, `%b`, `%B`, `%h`, `%c`, `%p`, `%r`, `%x` or `%X`:
```python
import pyarrow as pa
import pyarrow.compute as pc
for value, fmt in [
("15-Feb-2015", "%d-%b-%Y"),
("15 February 2015", "%d %B %Y"),
("Sun 15 Feb 2015", "%a %d %b %Y"),
("02/15/2015 02:30 PM", "%m/%d/%Y %I:%M %p"),
]:
try:
print(pc.strptime(pa.array([value]), format=fmt, unit="s")[0])
except pa.ArrowInvalid as e:
print(e)
```
Output on Windows (pyarrow 27.0.0.dev18):
```
Failed to parse string: '15-Feb-2015' as a scalar of type timestamp[s]
Failed to parse string: '15 February 2015' as a scalar of type timestamp[s]
Failed to parse string: 'Sun 15 Feb 2015' as a scalar of type timestamp[s]
Failed to parse string: '02/15/2015 02:30 PM' as a scalar of type
timestamp[s]
```
Expected, as on Linux and macOS:
```
2015-02-15 00:00:00
2015-02-15 00:00:00
2015-02-15 00:00:00
2015-02-15 14:30:00
```
On Windows, Arrow uses the vendored musl `strptime`
(`cpp/src/arrow/vendored/musl/strptime.c`), which defines `HAVE_LANGINFO` only
when `_WIN32` is not defined, and handles these directives only under `#ifdef
HAVE_LANGINFO`.
Found while working on #50146.
