Recentish C-s M-y change

[Lars Ingebrigtsen]

In Emacs 27, putting something in the kill ring and then `C-s M-y' would
yank that text to use when isearching.  This now enters a prompt instead
where I can autocomplete over all the things in the kill ring.

This is good functionality, and I can use `C-s C-y' to get the old
behaviour, but the `C-s M-y' is deeply ingrained in my muscle memory,
and it's tripping me up all the time.  (And if it's doing that to me,
it'll probably annoy somebody else, too.)

Could we move the new `C-s M-y' functionality somewhere else and retain
the old `C-s M-y' binding?
