[dev.regabi] cmd/compile: remove CTRUNE

Browse source 
Since CL 255217, we've been able to rely on types.UntypedRune to
identify untyped rune literals, rather than needing Mpint.Rune /
CTRUNE. This makes way for switching to using go/constant, which
doesn't have a separate notion of rune constants distinct from integer
constants.

Passes toolstash-check.
