Fix ReturnCount false positive when excludeReturnFromLambda is enabled

[sanggggg]

Fixes #5341

When excludeReturnFromLambda is enabled, then ignore every labeled return in lambda block.

There can be some extra cases like below, which may go against excludeReturnFromLambda's general purpose. (do not count return for lambda)

fun asdf() {
  kotlin.run {
    return@asdf // do not counted when if excludeReturnFromLambda is enabled.
  }
}

But for a clear definition of the excludeReturnFromLambda (if the labeled return from a lambda should be ignored), I excluded it.

Suggested change

	@Configuration("if labeled return from a lambda should be ignored (takes precedence over excludeLabeled.")
	@Configuration("if labeled return from a lambda should be ignored (takes precedence over excludeLabeled).")

On second thought, the configurations for excluding seem to be or conditions. (The added explanation is only making more confusion for the user). So I revert it.

.none().not() is sort of confusing here. Can we rewrite with any or count() >= 1

[TWiStErRob]

.count() will unnecessarily materialize the sequence. .any() returns a Boolean and will only materialize at most one element of the sequence.

Wouldn't it be isNotEmpty?

[TWiStErRob]

it's a Sequence, isNotEmpty is only on Collections, because for a "sequence" emptiness doesn't mathematically make sense: "Unlike collections, sequences don't contain elements, they produce them."
