We check for the existence of both `io_uring_prep_waitid` and `rb_process_status_new`. See also github.com/ruby/ruby/pull/15213. Note: the use of `pidfd_open`` (and then polling on the fd) means that doing `Process.wait(-1)` or `Process.wait(0)` will fail.

This PR adds an implementation of process_wait using
io_uring_prep_waitidwhen available. Since we also need to directly instantiate aProcess::Statusobject, we also check for the existence ofrb_process_status_new(see ruby/ruby#15213).Note: the use of
pidfd_open(and then polling on the fd) means that doingProcess.wait(-1)orProcess.wait(0)will fail.Types of Changes
