Array data imported through the FFI might contain unaligned buffers

**Describe the bug**

I described the issue in detail on the `arrow-adbc` bug tracker:

https://github.com/apache/arrow-adbc/issues/2526

**To Reproduce**

Executing a query through the Snowflake ADBC driver (Go) that happens to produce array with unaligned buffers. The linked issue above contains a stack trace.

**Expected behavior**

The Rust code importing the array should check the alignment and copy the buffers to an unaligned position if necessary.
