EmptyClassBlock should consider comment as "body" (via option?)

[TWiStErRob]

Expected Behavior of the rule

class Foo {
    // this is a comment about why Foo doesn't have a body (implementation detail)
}

the above shouldn't report EmptyClassBlock, IMO

Context

Documentation like this belongs to the class, but it's not KDoc as it's not the description of a public API.
Without the class body braces the comment would be just dangling in space, and for example Move (class) refactor wouldn't consider it to be part either and would leave it where it is.

class Foo
// just a random comment unrelated to Foo

Agree, here the fix: #1758
