Allow for advanced non-sequential SQE allocation schemes

Decouples SQE queueing and SQE prepping methods to allow for non-sequential
SQE allocation schemes as suggested by @daurnimator.

Adds essential SQE prepping methods from liburing to reduce boilerplate.

Removes non-essential .link_with_next_sqe() and .use_registered_fd().
