[C++][Python] pyarrow.csv.write_csv crashes when writing tables containing FixedSizeBinaryArray

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

Suppose we have a large array of binary strings
```
import numpy as np
import pyarrow as pa
import pyarrow.csv as pcsv

nparr = np.frombuffer(np.random.randint(65, 91, int(4E8), 'u1'), 'S4')
```
We want to construct a FixedSizedBinaryArray and Table
```
fixedarr = pa.array(nparr, pa.binary(4))
fixedtable = pa.Table.from_arrays([fixedarr], names=['fixedsize'])
```

Alternatively, construct a BinaryArray and Table
```
binarr = pa.array(nparr, pa.binary())
bintable = pa.Table.from_arrays([binarr], names=['binary'])
```
Setting up the csv write option
```
csvoption = pcsv.WriteOptions(include_header=False, batch_size=2048, delimiter='|', quoting_style='none')
```
Writing the table containing BinaryArray works
```
pcsv.write_csv(bintable, 'binary.csv', write_options=csvoption)
```

But writing the table containing FixedSizedBinaryArray crashes after first `batch_size`
```
pcsv.write_csv(fixedtable, 'fixedsize.csv', write_options=csvoption)
```
Note both tables are compatible with `pyarrow.parquet.write_table` though.

**Environment**:
Windows 10
pyarrow 12.0.0
Python 3.10.10

### Component(s)

Python

Reproduce the failure through the pyarrow.csv.write_csv entry point using the provided BinaryArray and FixedSizeBinaryArray examples, with batch_size set to 2048. Compare the two write paths and verify that FixedSizeBinaryArray tables complete without crashing and produce CSV output.
