go/analysis: add pass to check string(int) conversions

Issue golang/go#3939 proposes to remove string(int) from the language on the
grounds that it produces non-obvious results that can't be statically checked.
An intermediate step is to have go vet check for these sorts of conversions.
This change adds an analysis pass to check for string(int) conversions. It
suggests a fix to replace string(int) with string(rune(int)).

Updates golang/go#32479.
