io_uring: introduce type alias for io_tw_state

Browse Source 
In preparation for changing how io_tw_state is passed, introduce a type
alias io_tw_token_t for struct io_tw_state *. This allows for changing
the representation in one place, without having to update the many
functions that just forward their struct io_tw_state * argument.

Also add a comment to struct io_tw_state to explain its purpose.
