[release-branch.go1.18] cmd/compile: only inline method wrapper if me…
d2d5929 
…thod don't contain closures

CL 327871 changes methodWrapper to always perform inlining after global
escape analysis. However, inlining the method may reveal closures, which
require walking all function bodies to decide whether to capture free
variables by value or by ref.

To fix it, just not doing inline if the method contains any closures.

Fixes #54725
