io_uring/zcrx: split out memory holders from area
In the data path users of struct io_zcrx_area don't need to know what
kind of memory it's backed by. Only keep there generic bits in there and
and split out memory type dependent fields into a new structure. It also
logically separates the step that actually imports the memory, e.g.
pinning user pages, from the generic area initialisation.
