Pavel Begunkov 4aaa9bc4d5 io_uring/query: introduce rings info query
Same problem as with zcrx in the previous patch, the user needs to know
SQ/CQ header sizes to allocated memory before setup to use it for user
provided rings, i.e. IORING_SETUP_NO_MMAP, however that information is
only returned after registration, hence the user is guessing kernel
implementation details.

Return the header size and alignment, which is split with the same
motivation, to allow the user to know the real structure size without
alignment in case there will be more flexible placement schemes in the
future.
