[dev.typeparams] cmd/compile: delay method value wrapper generation until walk

Browse Source 
As walk already create the wrapper if necessary.

With this change, test/inline.go need to be changed to use
errorcheckwithauto, for matching "inlining call to ..." in autogenerated
position for method value wrapper, since when we don't generate the
wrapper immediately during typecheck.
