Allow userspace to pass a per-I/O write stream in the SQE:
__u8 write_stream;
The __u8 type matches the size the filesystems and block layer support.
Application can query the supported values from the statx
max_write_streams field. Unsupported values are ignored by file
operations that do not support write streams or rejected with an error
by those that support them.
