fuse: add FUSE_IO_URING_CMD_ADD_QUEUE

Browse source

fuse-over-io-uring queues are currently created lazily, as a side effect
of the first FUSE_IO_URING_CMD_REGISTER command for a given qid. This
ties queue creation to entry registration.

Add a FUSE_IO_URING_CMD_ADD_QUEUE command so a server can create a queue
explicitly, decoupling queue setup from entry registration. This is
additionally a prerequisite for FUSE_IO_URING_CMD_ADD_BUFPOOL, which
attaches a buffer pool to an existing queue and therefore needs the
queue to have been created first.
