- Break dependency between `if-else-wrapping` and `discouraged-comment-location`

The `discouraged-comment-location` rule contained several unrelated comment locations. When disabling the rule, ktlint might throw an exception when another rule depends on it. It is understandable that users do not instantly understand the relation between for example the `if-else-wrapping` and the `discouraged-comment-location` rule. So rules now have to emit warnings themselves whenever comments can not be processed.

For the `type-argument/type-argument-list`, `type-projection/type-parameter-list`, `value-argument/value-argument-list`, `value-parameter/value-parameter-list` new rules have been created to disallow comments. As those rules are more specific, it is more reasonable why specific rules depend on those rules.

Logic of this rule has been moved to normal rule classes in case a discouraged comment location was added for one specific rule only. Comment locations that are more generic (e.g. used by at least two different rules) are moved to separate rules as this provides more clarity about rule dependencies.

Logic from this class has been removed, except for what is needed to avoid a breaking change.
