Detect useless scoped functions

Implement the rule, which will detect useless scoped functions, and remove extra actions. For example, in a bundle of let - run it can be quite often met situations, when run contain single statement, which is actually will work without run:

someValue?.let {
                foo()
            }
                ?: run {
                    bar()
                }

Expected behavior

someValue?.let {
                foo()
            }
                ?: bar()
