[FlightRPC] Cannot use flight data with DataFusion (Rust)

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

Fetching data via Apache Arrow Flight (C++, Python involved) and passing them to Apache DataFusion (Rust) does not work:

Memory pointer from external source (e.g, FFI) is not aligned with the specified scalar type.
Before importing buffer through FFI, please make sure the allocation is aligned.

This is likely due to apache/arrow#32276 / apache/arrow-java#186.

Error:
```

Reproduce as follows:
```bash
git clone --depth=1 https://github.com/apache/arrow.git
git clone --depth=1 https://github.com/apache/arrow-testing.git

python -m venv venv
source venv/bin/activate
pip install pyarrow pandas datafusion

python arrow/python/examples/flight/server.py
RUST_BACKTRACE=1 python example.py arrow-testing/data/csv/aggregate_test_100.csv
```

with example.py:
```python
import sys

import datafusion
import pyarrow
import pyarrow.flight
import pyarrow.csv as csv

def push_data(client, path):
my_table = csv.read_csv(path).select(["c1"])
df = my_table.to_pandas()
writer, _ = client.do_put(pyarrow.flight.FlightDescriptor.for_path("file"), my_table.schema)
writer.write_table(my_table)
writer.close()

def get_data(client):
descriptor = pyarrow.flight.FlightDescriptor.for_path("file")
info = client.get_flight_info(descriptor)
for endpoint in info.endpoints:
for location in endpoint.locations:
get_client = pyarrow.flight.FlightClient(location)
reader = get_client.do_get(endpoint.ticket)
yield reader.to_reader()

def main(path):
client = pyarrow.flight.FlightClient(f"grpc+tcp://localhost:5005")
push_data(client, path)
partitions = get_data(client)

ctx = datafusion.SessionContext()
df = ctx.create_dataframe([[batch for batch in partition] for partition in partitions])
print(df)

if __name__ == '__main__':
if len(sys.argv) != 2:
print("Provide the path to example CSV file")
sys.exit(1)
main(sys.argv[1])
```

The error is thrown in Apache Arrow Rust implementaton: https://github.com/apache/arrow-rs/blob/eddef43d1cb46c1287da187ea1d86b0e1dc35a13/arrow-buffer/src/buffer/scalar.rs#L138
```rust
let align = std::mem::align_of::();
let is_aligned = buffer.as_ptr().align_offset(align) == 0;

match buffer.deallocation() {
Deallocation::Standard(_) => assert!(
is_aligned,
"Memory pointer is not aligned with the specified scalar type"
),
Deallocation::Custom(_, _) =>
assert!(is_aligned, "Memory pointer from external source (e.g, FFI) is not aligned with the specified scalar type. Before importing buffer through FFI, please make sure the allocation is aligned."),
}
```
In my environment, depending on the CSV column, e.g. `c1` (`c2`) with type `i32` (`i64`), `align` is `4` (`8`) while `buffer.as_ptr().align_offset(align)` is always `3` (`7`), where `arrow-rs` requires this to be `0`.
